TVS (Transient Voltage Suppressors) are a special form of diode created specifically to protect integrated circuits and other components from voltage transients. These volatile spikes of electricity can cause damage or reset an electronic item. A TVS diode, also known as a transorb, provides additional protection against overvoltage transients, in addition to clamping or shunting the voltage quickly.

SA150AHB0G is a TVS diode developed by Samsung Semiconductor, Inc. It is specifically designed to protect integrated circuits and other electronic components from voltage transients. This diode has a built-in charge pump circuit that drives a low-impedance bus line voltage from one polarity to the other, providing additional type II transient protection from 400 Watts. The SA150AHB0G also features an ESD clamping circuit which enables the protection of integrated circuits from voltage overshoots and ESD spikes.

Application Field

The SA150AHB0G is mainly used in automotive and industrial applications, such as motor control, controller area networks, electronic fuel delivery systems, and other electronics. This diode is designed to provide protection from voltage transients, overvoltages, and high surge energy, as well as protecting sensitive components from electrostatic discharge, or ESD. The SA150AHB0G also offers superior type II transient protection and has an operating temperature range of -55°C to +125°C.

Working Principle

The SA150AHB0G features a unique type II transient protection circuit which works by clamping or shunting the voltage very quickly. When a voltage transient occurs, the SA150AHB0G utilizes a charge pump circuit that drives the line voltage from one polarity to the other, which results in a very low-impedance bus line voltage. This charge pump also acts as an ESD protection circuit, morphing the voltage overshoot to a lower that can be tolerated by the targeted device.

The SA150AHB0G also features a zener diode, which helps to provide a very high clamping or shoal voltage. The zener diode is activated when the voltage exceeds a certain level (the breakdown voltage), The zener diode then starts to conduct, clamping down the voltage. The zener diode is also used as an ESD protection circuit, as it clamps the voltage below a certain level in order to protect sensitive components from being damaged.

The SA150AHB0G is an ideal solution for protecting electronic components and integrated circuits from voltage transients and overshoots. It is highly durable and reliable and is suitable for use in a wide range of applications.
