A Transient Voltage Suppressor (TVS) diode, such as a PGSMAJ36CA E3G, is a three-terminal semiconductor designed to provide protection against high electrical transient surges caused by ESD (Electro-Static Discharge). It prevents such signals from overloading and damaging both nearby components and systems. In TVS diodes, the Zener diode portion acts to protect from over-voltage, and the avalanche breakdown diode portion acts to protect from over-current. In this way, TVS diodes protect systems and provide a safe means of operation.

The PGSMAJ36CA E3G is a 36V, 18pF unidirectional silicon Junction Transient Voltage Suppressor (TVS) diode package with a Reverse Stand-Off Voltage of 35V and breakdown current rating of 30Amps. It is used for protecting against transients on electronic systems, electrical circuits, signal lines, and power supplies. The device is optimized for ESD transient protection, with low stand-off voltage and low clamping voltage. It also has a fast reaction time and rugged, bipolar technology.

The application field of a PGSMAJ36CA E3G Transient Voltage Suppressor (TVS) diode covers a broad range of industrial, automotive, and consumer electronic systems. The device is used to protect low power ICs, data lines, transceivers, surge-protection circuitries, and other parts of a system which can be damaged during voltage transient conditions. It also protects signal lines, portable electronics, and transistors in power supplies, as well as automotive systems.

The working principle of the PGSMAJ36CA E3G is based on the fundamentals of Zener and Avalanche Breakdown Diodes. In Zener operation, the TVS diode acts to limit the voltage to its threshold rating. In the case of an over-voltage transient event, the Zener secton of the device becomes conductive, clamping the voltage to a definite level. In Avalanche operation, current is diverted away from the components by the breakdown of the P-N junction. This is referred to as its clamping voltage, which is typically much lower than the Zener voltage.

The PGSMAJ36CA E3G Transient Voltage Suppressor (TVS) diode is a reliable and safe means of protecting electronic systems against minor or major voltage transients. It offers various protection against both over-voltage and over-current transients. Furthermore, it has a low stand-off voltage, low clamping voltage, and fast reaction time. This device is suitable for ESD protection in applications such as low power ICs, data lines, transceivers, surge-protection circuitries, signal lines, transistors in power supplies, automotive systems, and other parts of a system which can be damaged during voltage transient conditions.
