Reverse leakage testing Reverse leakage may be measured only after removing the component from the circuit board because shunt resistances abound in almost all circuits. Good silicon rectifiers and ...

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 ...
