SOURCE: 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?

Equilent for a zener diode (RD 30ESB2)


Zener diodes are invariably used as low power voltage regulators or as a voltage reference for voltage regulating circuitry.

Zener diodes are sold by wattage and reference voltage by numerous component suppliers and constructor stores and in theory the voltage is marked on them, though difficult to see and easily defaced.

Finding an equivalent for what appears to be a manufacturer's part number presents a rather difficult challenge. The official service sheet will probably provide the required voltage. Without that information you will either have to purchase the component from the manufacturer under the part number or experiment until the required value is discovered.

MCS 160 Boston Subwoofer ZD3 Zener Diode Value


ZD3 is a 18v zener. Also check the surface mount resistor on the back of the board that is attached to ZD3, I think it is R9. Should be 10 ohms. This resistor sometimes opens when the diode goes short.

LG 32lh200 power supply failure common problem


You might try to follow the diode back to the source and read voltage to know the value of the diode and also look on the diode for generic number--short of that Google the model number with "parts" as it might be cheaper to replace the board than try to fix it by guessing values.

The secondary output voltage comes out from is more than it should be there. That is why, the protection zener diode blows off, as soon as you switch ON the set. First find and repair the power supply regulator, for correct output voltage. Refer its repair book for details. After repair include the zener diode in place. OK.

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.
