What the voltage value of zener diodes? (D825, D826 red,red,gray) and D823 (red,yellow).


This table is the information used by MOST diode manufacturers that use color banding on diodes. Most manufacturers stamp the ID right on the diode but some do use color banding as the method of identification. For purposes of alignment, the side with any color band closest to either side of the diode is the equivalent of the left side of this table. The three examples in the table when associated with the values in the lower table, are identified as 1N64E for the top diode, 1N452G for the middle diode and 1N4762 for the bottom diode.
See the color coding

Pls help me find exact value of the 2 zener diodes in power supply of tc21f3p


It is very difficult to give you the exact voltage of the zener diodes you're discussing here; as there is no other details about the position or part number of them at the circuit board. If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

In panasonic modeltc-29sf3 pls give me the working voltage of zener diode with color code gray red red and red yellow in power supplyn section


just read the model and then google it, beside, if you short them, you need to replace them with same value, and this will be determined by the circuit, if you did not change the circuit - just buy two new diodes and install them, do not bother with voltages as they have some tolerance and type will determine it.

R2M diode is 130v zener, the missing diode is RM25 which is 55V zener for over voltage protection.

UNKNOWN VALUE OF VOLTAGE ZENER DIODES


I was not able to find any service or schematic for this model. The colors means that the value is 22.6 volts zener diode with the other blue band indicating where the cathode is.
Could you tell me where or what other components this zener diode is connected to?
