TVS – Transient Voltage Suppressors, otherwise known as TVS diodes, are a type of short-term over-voltage protection device that are used to protect sensitive electrical and electronic circuits from overvoltage transients, including electrostatic discharge (ESD) and electrical fast transients (EFT).

The 3KASMC30AHE3_A/I is a specific model of TVS diode. It is especially designed for general purpose, high-speed ESD protection of automotive applications. It is specifically designed to provide low capacitance and fast response time with a breakdown voltage range of 3.3 V to 5.5 V. Its peak pulse power rating is >30 W and the transient peak current is >3000 A. It features a degradation free auto-zero, high capacitance, integrated ESD protection and EMI filter, and low holding current.

The 3KASMC30AHE3_A/I has a number of applications in different automotive systems, such as electric cars, hybrid vehicles, and conventional cars. It is used to protect battery charger systems, entertainment systems, security systems, embedded systems, electrical buses, and automotive infotainment systems. It is also used for general purpose and high-speed ESD protection.

The working principle of the 3KASMC30AHE3_A/I is based on the principle of avalanche breakdown. When the voltage applied across the device exceeds its avalanche breakdown voltage, the device quickly switches from its low resistance state to a high resistance state, thus reducing the voltage applied to the protected circuit. This reduces the current through the device and protects the underlying circuit from short-term transients.

The 3KASMC30AHE3_A/I includes integrated ESD protection, which helps protect against ESD stress events. It also includes an EMI filter to help reduce EMI interference in automotive applications. The device utilizes an auto-zero mechanism to enhance common-mode transient noise immunity.

The 3KASMC30AHE3_A/I is an optimal choice for automotive applications that require reliable and effective protection from short-term overvoltage transients, including ESD and EFT. Its integrated ESD protection and low capacitance help provide reliable protection, while its low capacitance and fast response time help reduce EMI interference in automotive systems.
