Mine runs 120mA. Note that this is sufficient current to destroy a sensitive germanium diode—avoid using this range in this case. Reverse leakage testing Reverse leakage may be measured only after ...

Schottky diodes are unsuitable. Despite their low recovery time, they generate a nonzero reading because of their relatively high capacitance and non-negligible leakage currents. Low-capacitance, ...

Figure 2 illustrates the high-voltage diode leakage current measurement results obtained using the test setup shown in Figure 3. The diode has a maximum specified reverse current of 10 µA when ...

The rechargeable 10-hour lithium-ion battery powers the unit for a full day of testing. The new DR58 Heated Diode Leak Detector has a state-of-the-art heated diode sensor that is very sensitive to ...

The four main types of electronic leak detectors available to HVACR techs include: heated diode, corona discharge, infrared, and ultrasonic. The following is a snapshot of how the different ...

The highlighted project here is a capacitor leakage tester, which is very handy for sorting through piles of old parts looking for anything still within spec, or just verifying a part on a board ...
