Testing germanium diodes If you have an analog VOM, you may be surprised how high the short circuit current is on the Rx1 range. Mine runs 120mA. Note that this is sufficient current to destroy a ...

The voltage in Figure 4was measured at a zener-diode current of 2.8 mA. Figure 4 Measure the voltage across a zener diode with a digital multimeter. You can use the circuits in figures 2 and 3 to test ...

For testing diodes, the waveform generator is configured to a ±2.5-V ramp signal at 100 Hz. This is a low-frequency test, so the high-resolution mode is used to reduce noise.

Before the era of large-scale integration (LSI) semiconductor circuits, discrete logic circuits using the common ...

By combining 49 of them he’s put together a soda bicarb diode steering circuit for a 7-segment display capable of showing the digits 0 to 9.

The circuit values shown limit the forward current to a safe 150 A and maximum reverse voltage to 1.2 V. Some simple modifications to the circuit can change these limits.
