The main characteristic of a diode is its unidirectional conductivity, which means that under the action of forward voltage, the on resistance is very small; Under the action of reverse voltage, the conduction resistance is extremely high or infinite.
If the diode on the circuit board is damaged, you can still see the original model of the tube and replace it with a diode of the same model.
A bridge stack is an electronic component composed of multiple diodes inside. The main function is rectification, adjusting the direction of current.
TVS diode, also known as transient suppression diode, is a widely used new type of high-efficiency circuit protection device, which has extremely fast response time (sub nanosecond level) and considerable surge absorption capability.
Transient Voltage Suppressor (TVS), abbreviated as TVS, is a high-performance protective device in the form of a diode.
Zener diode (also known as Zener diode) is a semiconductor device that has high resistance until the critical reverse breakdown voltage. At this critical breakdown point, the reverse resistance decreases to a very small value, and in this low resistance region, the current increases while the voltage remains constant.
