What is a trigger diode? The basic structure, characteristics, working principle, application, detection, and measurement methods, installation steps, and development history of trigger diodes 4

4. Welding: Use solder to solder the pins of the trigger diode to the corresponding positions on the circuit board. Pay attention to maintaining good contact between the pins and the circuit board, and ensure that the soldering points are firm and reliable.

5. Check: After welding is completed, use a multimeter or other testing equipment to check for short circuits or open circuits between the pins of the trigger diode.

6. Insulation treatment: Insulate the trigger diode as needed to prevent interference or damage to the surrounding circuit.

7. Cleaning and organization: Clean up the welding slag and debris generated during the welding process, and organize other components and circuits on the circuit board.

8、 Development history:

The trigger diode was first invented by American physicist Walter H. Schottky in 1938, who introduced a potential barrier between metal and semiconductor to achieve the triggering function of the diode. With the development of semiconductor technology, the performance of trigger diodes continues to improve, and their application scope is becoming more and more extensive.

In the early days, trigger diodes were mainly used in the field of wireless communication for detecting, modulating, and demodulating wireless signals. With the rise of digital electronic technology, trigger diodes have been widely used in digital circuits, counters, timers, and other fields. The high-speed switching and high-frequency characteristics of trigger diodes make them one of the important components in digital circuits.

In recent years, with the continuous development of electronic technology, the performance of trigger diodes has been further improved. Some new materials and structures of trigger diodes have emerged, such as Schottky barrier diodes, PIN diodes, etc. These new trigger diodes have higher switching speed, lower power consumption, and better linear characteristics, making them suitable for a wider range of application fields.
