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?

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

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.

Burnt Zener diode... Voltage spec??


On the cathode of the zener diode look for a filter cap and check its value the voltage of the zener should be less than the working voltage of the zener. Basicly its likely being used as a shunt regulator as protection and regulation of the voltage. When the zener hits a certain threshold it will breakdown and start conducting to ground until the supply regulates and then it will recover. If the filter cap for that voltage rail was 25V I would guess that the zener would probably be regulating between 12 and 20 volts. I'd pick a 15V Zener its probably +- %10 on the original and any system should be able to take a %10 tolerance as a general design rule.

Ziener diode


Yes, Zener diodes can work both on forward and reverse biasing. The primary difference between a zener diode and the ordinary junction diode is it is designed specifically to operate with a reverse bias voltage that is high enough to cause the the device to breakdown and conduct a high reverse current. Hope this answers your question and provides you with some help. If you need further assistance please let me know.

If you do not mind, would you please rate my help. I would very much appreciate it. Thanks
