Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On Semiconductor‘s BZX55C15RL, which has a working voltage of 13.8 to 15.6V. The voltage in Figure 4was measured ...

Diodes whose reverse-breakdown characteristics are controlled ... The DVM reads the voltage drop across the device under test. This circuit is suitable for testing of ZD up to 30V rating, if test ...
