Try mouser and look at the pic that they have shown or better yet look at the datasheet. If it looks the same I believe IRFZ44VZSPBF is what you are looking for. http://www.mouser.com/ProductDetail/International-Rectifier/IRFZ44VZSPBF/?qs=sGAEpiMZZMshyDBzk1%2fWi5%252bqVgN3%252bWS8q9KimKl17b0%3d

Screen horizondally pulled right side and screen rolled to left side


hi,
your monitors horizontal deflection side have some problem. you have to check the horizontal width cotrolling transistor mounded on the aluminum heatsik near the lot( line output transistor). also check the three mosfets which adjust the width for different resolutions. there are three such mosfets in the horizontal section.

fist of all replace the width controlling transistor in the heat sink. photo of mosfet and transistor is added for reference. not the exact number.
ok

I have a ct312 inverter tig welder and the abnormal pilot light has come on and ive been through what it says in the maintenance book but has not fixed it. the book says there must be something wrong with...


i can't tell you what's wrong with your machine but i can tell you that a MOSFET is a 'metal oxide semi conductor field effect transistor'. So, it's a transistor, probably a biggish one that handles the power of your cutter/welder and maybe possible to replace without soldering.
i have heard that a lot of these chinese machines suffer from loose connections so it may even be a loose connection to a component rather than a faulty component.
by the way, is it any good when it's working? i am interested in buying one for myself.

good luck.

Well my ACER AL1916B LCD monitor blew up.


The MOSFET that blew up will more likely to have the switch mode driver IC that went out with it also, you need to verify that the IC is good otherwise you will blow up the new MOSFET, you may be better off buying a new board from here: http://www.discount-merchant.com/ProductDetails.asp?ProductCode=1160140&Click=54985
By the time you order the new MOSFET and other parts it may end up more han $35, just a suggestion.

Need mosfets for hifonics amp sfp50n06


That is a Semiwell part I believe. It is an N-Channel power mosfet. Go look on their website they may have an alternate part you can use.

Power up problem with alesis rs300 (ra300)


you have more than likely damaged some transistors.
the resistors have burned because of excessive current.
there are 2 typesof transistors,bipolar and mosfet
a bipolar transistor has 3 pins.1) base 2)emitter 3)collector.
an NPN is tested with the + meter lead on the base , and a PNP transistor with the - lead on the base.
TESTING
base to collector should read .5 to .6 v drop in one direction and open in the other with a digital meter on the diode check function.
base to emitter about the same,but slightly higher than the collector.
if base to collector is .5v then base to emitter is .52 or so.it is always higher than the base collector number.
between emitter and collector will read open in both directions.
if there is a short on any lead combination,the transistor is blown.
npn transistors operate on the positive rail power supply,and pnp on the negative rail.
typically a 150 watt amp will run + - 65vdc.
the transistors running on the plus side are npn and on the negative pnp.
most pnp output transistors are green.,but some are black,
so we must go by the numbers on the transistors, eg.A1076 is a pnp,B755 is a pnp and all transistors that have a C or D eg. D424 are NPN transistors. all A and B numbers are PNP and all C and D numbers are NPN.
MOSFET transistors have 3 pins 1)gate 2)drain 3)source
the source goes to power like the collector does. the drain is like the emitter,and the gate switches it on like the base does.
testing a mosfet is a different procedure.
a mosfet with k then a number e.g. k135 is a positive device like npn.
a mosfet with j and a number e.g. J50 is a negative device like pnp.
a mosfet reads open source to drain both directions.
for a positive (k number device) the plus meter lead goes on the source.,the black meter lead on the drain. on the diode test function.
jump a wire from the source to the gate for 1/2 second and remove the jumper while leaving the other two meter leads connected to the source and drain.The mosfet should switch on and the meter should show a short.that means the mosfet switched on.About 5 seconds later,the resistance from drain to source should go open.
for a p channel mosfet,it checks the same,except that the black meter lead goes on the source and gate .
a mosfet will stay switched on longer than the voltage applied to the gate,if it is driving a high impedance device such as a meter.
a bipolar transistor will not stay on when voltage is removed from the base lead.
i hope this has been of some help.

No pictoure or sound.


check your pwd supply's Transistor or Mosfet
or Check your Horizonetal Transistor or Mosfet may be it is damaged
If it is damaged replace it

T1500-1bd burnt mosfet


First of all is the mosfet your talking about in the output section or in the power supply section? Most car amps use mosfets in the power supply section, some use them in the output section. To test the transistors in your amp, take a digital volt meter and set it to diode check. Then take the leads and put them accross the first and third legs of the transistors. Usally the red test lead on the first leg and black test lead on the third leg of transistor. If you get a reading of 000 then transistor is shorted. If you get a reading below 600 then transistor is on it's way out if not allready or it's next to a shorted transistor that is it's complimentry output transistor. comonly you will have 2 transistors working together, one NPN and one PNP per a channel, or 4 of them in a bridged type output circuit depending on the watts and how man channels your amp has. I was just looking at the specs of this amp and it's got me confused. It says it's a 2 channel but looking at all the info on different pages it says at 4ohm:200wattsx4 and at 2ohms:300wattsx4 and 1 channel mono 600watts into 4ohms. weird for a 2 channel. anyway that is how you test your transistors. Same way for the power supply section but, you will come accross a couple or more switching diodes that look like transistors and you will get a 000 reading when you test those like I specified. They rarely go out and most of the time there is only 2 of them. They will have a diagram like a diode on the front showing you which way the power flows. Let me know what you find out. Your amp should have went to protect mode if you smoked a mosfet.

600w legacy amp


9 times out of 10 if your amplifire is in protect mode and evrything externaly, like speakers, fuse, voltage, etc. checks out fine then
either you have shorted out output transistors or power mosfet transistors. Basicly that just about what happens with car amps.
It's easy enough to fix IF, IF you know what your doing. First you
need to check the output transistors with a digital volt meter on diode check, If they check out then check your power supply mosfet transistors. I can almost guarantee this is your problem. Very common. I buy non working amps all the time and repair them. Listen to pbabin also he has helped me out. Good luck

Horizontal output transistor keeps failing


The horizontal output transitor is always connected to the primary winding of the flyback transformer (via collector) and also to the horizontal deflection coil via an electrolytic capacitor. The most likely suspect for damaging the transistor is the fylback transformer. In some countries there are electronic stores that test flyback transformer by winding a few turns on the ferrite core and applying a test voltage. This test will only test the secondary. The primary winding is difficult to test for turn to turn short because the resistance is quite low and you do not know the 'good' resistance.
