TVS (transient voltage suppressor) diodes are a type of power protection device used to protect sensitive electronic components from brief, large surges of voltage. The SMAJ150A M2G is a type of TVS diode that is specifically designed for transient overvoltage protection. This article will discuss the application field and working principle of this particular diode.

Application Field

The SMAJ150A M2G is a popular choice for protecting a variety of electronic devices from transient overvoltage. It is often used in automotive, telecom, computer, and other electronic systems as a protection device. It can be used in applications where transient overvoltages of up to 1500W (10/1000µs waveform) can reach the circuit.

The SMAJ150A M2G can be used in parallel with other protection devices, such as MOVs and varistors. It is also suitable for use in AC-DC power supplies, consumer electronics, and other industry systems. It can be used in applications with a working voltage of 600V. It is also suitable for use in high-density applications, as its small size makes it an ideal choice for tight spaces.

Working Principle

The SMAJ150A M2G has a working voltage of 600V and a maximum clamping voltage of 10V at 400A peak. It is designed to suppress transients caused by inductive switching of motors, and other transient events by clamping the voltage within a short time period. The SMAJ150A M2G works by sensing the transient event and triggering its various elements to absorb the transient energy. It is designed in such a way that it only clamps the voltage for a very short period of time, ensuring that the voltage level does not permanently damage sensitive electronic components.

The SMAJ150A M2G is composed of a Zener diode and an avalanche diode. The Zener diode limits the overvoltage on the line. When a transient event is detected, the Zener diode will trigger the avalanche diode, which then acts as a voltage-clamping device. The avalanche diode can absorb a large amount of energy and clamp the transient voltage quickly. This prevents damage to sensitive electronic components.

The SMAJ150A M2G is a reliable and efficient power protection device. It is designed to protect various electronic components from transient events, and it works quickly and efficiently to protect those components from damage. It is a popular choice in automotive, telecom, computer, and other electronic systems due to its small size and its ability to effectively clamp transient voltages in a short amount of time.
