TVS - Diodes

TVS - Diodes, short for Transient Voltage Suppressors, are used in electronic circuits to protect components from voltage transients caused by electrostatic discharge (ESD), surges, inductive load switching, and lighting. TVS diodes are designed to limit the voltage presented to attached components by quickly and passively clamping a voltage above a zener voltage or to ground.

PGSMAJ30CA E3G Application Field and Working Principle

PGSMAJ30CA E3G, is an unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronics from the harmful effects of transients caused by electrostatic discharge (ESD). It features glass passivated junction and a flame retardant resin package for low reverse leakage and High reliability. It is also designed to protect automotive AC power systems from transient overvoltages.

This diode is capable of withstanding multiple ESD strikes without degradation or failure. It has a reverse stand-off voltage range of 30V - 33V and a maximum peak pulse power of 600 Watts. The response time of the PGSMAJ30CA E3G is approximately 1.5ns (Nano Seconds).

PGSMAJ30CA E3G has a low capacitance and is designed to dissipate energy produced from high energy pulse events. It is ideally suited to protect I/O ports from ESD strikes and transients produced by inductive loads being switched. With its very low on-state voltage, it offers lower clamping voltages than other types of TVS diodes.

PGSMAJ30CA E3G is commonly used in automotive AC applications where transients caused by the load drive the voltage on the power system up to levels that can damage components in the system. It is also used in Telecommunication applications such as ISDN terminal adapters, DSL modems, and Optical Network Terminals (ONT).

In summary, PGSMAJ30CA E3G is a Transient Voltage Suppressor (TVS) diode designed to protect electronics and automotive AC power systems from transient overvoltages. It is characterized by low capacitance and 1.5ns response time, making it ideal for protecting I/O ports from ESD strikes and transients produced by inductive loads being switched. It is commonly used in automotive AC applications and Telecommunication applications.
