SZMMQA6V2T1G Circuit Protection

TVS - Diodes

TVS - Diodes are electronic components designed to protect circuits from damage caused by transient voltages, such as lightning, electrostatic discharge (ESD), and other induced electrical surges. Typically, these components use an avalanche breakdown method, where a high voltage triggers an avalanche effect in a diode junction. This causes a large amount of current to flow through the diode, thus reducing the high voltage to a safe level.

SZMMQA6V2T1G Application Field and Working Principle

The SZMMQA6V2T1G is a type of Transient Voltage Suppression (TVS) diode used to protect sensitive electronics from transient voltages and spikes. Its key features include 1500W peak power handling capability, an unclamped inductive switching pulse of 3.0V, and a working voltage range of 6.3 to 7.2V. The low clamp voltage of 5.0V and low leakage current of 0.0005mA make it suitable for use in high-capacitive load applications.

The SZMMQA6V2T1G works by providing a short-circuit path to ground for voltage spikes that exceed its breakdown voltage. When such a spike is detected, the diode conducts, allowing the current to flow through the diode to ground, thus clamping the voltage and preventing it from damaging sensitive components. The diode can handle very high peak currents for short duration, typically up to 1500W.

TVS diodes such as the SZMMQA6V2T1G can be used in a variety of applications. They are commonly used in automotive, industrial, and consumer electronics to protect sensitive components from voltage spikes. In automotive applications, they are used to protect ECU circuits, control units, and computers. In industrial applications, they are used to protect against short circuits from induced lightning strikes. They can also be used in consumer electronics, such as cell phones, to protect against electrostatic discharge (ESD).

The SZMMQA6V2T1G provides a high level of protection in a wide range of applications. Its low clamping voltage, low leakage current, and high peak power handling capability make it an excellent choice for the protection of sensitive electronic components in a variety of applications.
