TVS - Diodes

Transient Voltage Suppression (TVS) Diodes protect sensitive circuits from transient voltage surges, such as lightning strikes or over-voltage spikes. They are composed of a semiconductor diode coupled to a low-inductance resistor and provide a low-impedance path for transient current flows. The PGSMAJ75CA R3G is a TVS diode designed to provide ESD (electrostatic discharge) protection for sensitive electronics, such as industrial and automotive devices.

Working Principle of TVS Diodes

TVS Diodes work by allowing the transient over-voltage to be steered or clamped into a safe voltage level. The diode works to dissipate this energy in the form of low-impedance current paths. These current paths flow to the ground, thus minimizing any resulting voltage spikes in the circuit. Also, when the voltage rises above a certain threshold level, the diode works to clamp the voltage and steer it away from the circuit components. The PGSMAJ75CA R3G has a peak pulse power of 200 W and a maximum ESD protection voltage of 8 kV.

Application field of PGSMAJ75CA R3G

The PGSMAJ75CA R3G is designed primarily for ESD protection applications and is suitable for use in sensitive automotive control devices, such as airbag controllers, ABS systems, electric speedometers, and other electronic systems.
