Detection method for bidirectional trigger diode transition voltage 3

3. Oscilloscope method: Connect a bidirectional trigger diode to a circuit formed between a resistor and a power source, and use an oscilloscope to monitor the voltage across the bidirectional trigger diode. By gradually increasing the power supply voltage until the oscilloscope displays a voltage jump, the transition voltage can be determined. This method can visually observe the occurrence of transition voltage and can be used for dynamic testing.

4. Pulse testing method: Considering that bidirectional trigger diodes may be used under high-speed switching conditions, pulse testing method can provide a measurement method that simulates actual working conditions. By applying short pulse voltage to the bidirectional trigger diode and monitoring its response using devices such as oscilloscopes, the transition voltage can be determined. This method is particularly suitable for testing the dynamic characteristics of bidirectional trigger diodes.
