What is a clamp diode, its structure, advantages, principles, applications, installation, and development history 2

3、 Principle:

The working principle of clamp diodes is based on the characteristics of PN junctions. Under normal operating conditions, when the voltage in the circuit is below the design limit of the clamp diode, the clamp diode is in a reverse cutoff state and has almost no impact on the circuit. When the voltage in the circuit exceeds this limit, the clamp diode quickly conducts, forming a low resistance state, and excess voltage is discharged through the clamp diode to protect circuit components from damage.diode

Clamp diodes can be designed to clamp forward or reverse as needed. Positive clamping is used to limit positive voltage, while reverse clamping is used to limit negative voltage. In addition, by combining with other electronic components, clamping diodes can also form complex voltage clamping networks to meet specific voltage control requirements.diode

4、 Application:

Clamp diodes are widely used in various electronic devices, mainly for power supply stabilization and overvoltage protection. For example, in computer power supplies, clamp diodes can prevent sudden voltage increases that can cause hardware damage to the computer. In communication devices, clamp diodes can prevent interference from overvoltage on signal transmission. In addition, clamp diodes are widely used in fields such as medical equipment, automotive electronics, and industrial control.diode
