As is well known, diodes have the characteristic of unidirectional conduction and can be applied in these fields: 1. Rectifying diodes are mainly used in rectification circuits, that is, pulsating rectifying diodes that convert alternating current into direct current are surface junction type, so their junction capacitance is large, which makes their operating frequency lower, generally less than 3Hz. 2. Under the action of DC voltage, the diode resistance of the switch is small and it is in a conducting state,

ESD (electrostatic discharge) protector is a device specifically designed to prevent damage to electronic equipment caused by electrostatic discharge. The following is a detailed explanation of ESD protector: 1. Definition and Function ESD protector is an overvoltage and anti-static protective component, whose main function is to transfer ESD stress from sensitive components, allowing current to flow through the protective component rather than the sensitive component

Choosing a suitable transient suppression diode to protect the circuit from overvoltage damage requires consideration of multiple factors. Here are some guiding steps: Voltage Level: Determine the maximum operating voltage and maximum overvoltage required for your circuit. The rated voltage of the transient suppression diode should be slightly higher than the maximum overvoltage to ensure its normal operation and effective suppression of overvoltage.

Transient Voltage Suppressor (TVS) is a special type of diode that works mainly based on the avalanche breakdown effect of PN junction. The following is a detailed introduction to its working principle: 1. Avalanche breakdown effect Avalanche breakdown effect is the core principle of TVS diode operation. The avalanche breakdown effect is the core principle of TVS diode operation. In a PN junction, when the applied voltage exceeds its breakdown voltage
