SMAJ170CATR Circuit Protection

TVS - Diodes

TVS (Transient Voltage Suppression) diodes are designed for protection from transient surge voltages that can cause massive destruction to electronic equipment. As an active semiconductor device, a TVS diode exhibits rapid breakdown characteristics that protect sensitive electronic circuitry from damaging transients. A TVS diode is designed to clamp the transient spike while allowing the normal signal or power to pass with minimal effect on the normal operating voltage.

The SMAJ170CATR is a popular, low capacitance transient voltage suppression (TVS) diode designed for ESD (Electrostatic Discharge) and transient over-voltage protection. The SMAJ170CATR is designed to protect sensitive electronic components from damaging voltage spikes and ESD.

Application Field

The SMAJ170CATR offers one of the best solutions for protecting equipment and IC\'s from electrostatic discharge (ESD) and transients in a variety of industries. The SMAJ170CATR has been used to protect against high-voltage transients in various medical and industrial equipment, automotive, and consumer electronics, including portable and hand-held products. It is ideally designed for applications that require low to moderate current, power, and circuit protection.

Working Principle

The SMAJ170CATR operates as an unidirectional balance contra-directional symmetrical device, meaning it clamps any voltage that is higher than its reverse breakdown voltage (in the forward direction). This allows it to offer a level of protection that is superior to most types of surge suppression products. The SMAJ170CATR is designed to operate between -55°C and + 125°C, with a peak pulse voltage of 17V and a peak pulse current of 70A.

It is a unilateral device, and the current is only allowed to pass in one direction, so it must be installed in the circuit in order to provide protection. The SMAJ170CATR is designed to clamp transient surges quickly and effectively, protecting against destruction and damage to sensitive components and increasing circuit protection. It is also designed to limit the rate of rise of the transient surge voltage, enabling it to provide effective protection with minimal interference.

The SMAJ170CATR is a popular TVS diode used in a variety of industrial, medical, and consumer electrical products. It can provide reliable over-voltage protection and prevent damage to sensitive components from ESD and transient surges.
