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

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.

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.

3. Semiconductor parameter tester method: Using a dedicated semiconductor parameter tester, the trigger diode is forward biased and the turning voltage of the diode is measured through the tester.

7、 Installation steps:

The installation steps for triggering diodes are generally as follows:

1. Preparation work: Clean the workbench, ensure it is dust-free, and prepare the necessary tools and materials.

2. Determine installation location: According to the circuit design requirements, determine the installation location of the trigger diode and mark it on the circuit board.

3. Prepare trigger diode: Remove the trigger diode from the packaging, check for damage, and confirm the pin markings and specifications.
