n=left]The testing of zener diodes requires a variable dc power supply. A typical test circuit can be constructed, as shown in figure 4-19. In this circuit, the variable power supply is used to adjust the input voltage to a suitable value for the zener diode being tested. With the zener diode connected no current will flow until the voltage across the diode is equal to the zener voltage. If the diode is connected in the opposite direction, current will flow at a low voltage, usually less than 1 volt. Current flow at a low voltage in both directions indicates that the zener diode is defective. ..................[:=> Show Contents <=:]

nt will flow at a low voltage, usually less than 1 volt. Current flow at a low voltage in both directions indicates that the zener diode is defective. Before you start to test any zener diode, you must first understand the marking or part number and then look for the voltage ratings. Refer to my article about how to read the zener diode data. Once you know the zener diode voltage from your favorite data book such as the Philip ECG semiconductor master replacement guide then it is easy to check with your meter to see if it leak, open or shorted.
