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 1- to 2.4-V SZL diodes feature a test current of 250 µA and maximum surge current of 25 A. Reverse leakage current is less than 50 nA. Their ruggedized, hermetically sealed, surface-mount UB ...

The circuit’squiescent current is lower than mostSchottky diodes’ reverse-leakage current.This circuit provides active rectificationat voltage drops as low as 0.8V.At lower voltages, the MOSFET’s ...

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 ...
