5、 Testing:

In order to ensure the normal operation of diodes, there are several commonly used detection methods, including the following:

1. Voltage test: Use a multimeter or oscilloscope to measure the forward voltage and reverse resistance of a diode.

2. Current testing: Use an ammeter to measure the forward and reverse currents of a diode.diode

3. Peak Reverse Voltage (PRV) Test: Test the maximum reverse voltage that a diode can withstand.

4. Reverse current test: Test the leakage current of a diode under reverse voltage.

6、 Method for measuring the transition voltage of a trigger diode:diode

The transition voltage (also known as the turn-on voltage or trigger voltage) that triggers a diode refers to the voltage at which the diode transitions from the off state to the on state under forward bias. There are several methods for measuring the transition voltage of a trigger diode, including the following:diode

1. Multimeter method: Use a multimeter to forward bias the trigger diode and gradually increase the voltage until the diode transitions from the off state to the on state, at which point the voltage is the transition voltage.diode

2. Oscilloscope method: Use an oscilloscope and a signal generator to form a testing circuit. Connect the output signal of the signal generator to the forward bias terminal of the trigger diode, and observe the conduction state of the diode through the oscilloscope. When the output voltage of the signal generator gradually increases and the trigger diode transitions from the off state to the on state, a jumping signal waveform will appear on the oscilloscope, and the voltage at this time is the transition voltage.diode
