STMicroelectronics 1-Element Uni-Directional TVS Diode 400 W, 2-Pin DO-214 SMAJ170A-TR

STMicroelectronics SMAJ170A-TR is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for surface mount technology applications. It achieves a peak pulse power dissipation of 400 W, ensuring effective protection of sensitive electronic components against voltage spikes and transient surges. Its DO-214 package with 2 pins facilitates secure mounting on printed circuit boards.

This TVS diode features a single diode configuration that provides uni-directional transient voltage suppression, making it ideal for protecting power lines and other circuits subject to voltage transients. With a minimum breakdown voltage of 189 V and a maximum reverse stand-off voltage of 170 V, the SMAJ170A-TR offers reliable voltage clamping at 353 V under transient conditions.

Designed to operate within a temperature range from -55°C to 150°C, this diode ensures durable performance in demanding industrial environments. The diode also exhibits a low maximum reverse leakage current of 200 nA, contributing to energy-efficient circuit protection.

Additional technical features include a test current of 1 mA, a maximum peak pulse current rating of 6.5 A, and ESD protection for enhanced component longevity. The compact size with 4.6 mm length, 2.95 mm width, and 2.03 mm height makes it suitable for dense PCB layouts and modern electronic assemblies.

This TVS diode is well suited for use in industrial, electronic manufacturing, and telecommunications applications where transient voltage protection is critical. It helps to safeguard systems from damage caused by electrical overstress events, supporting reliable operation and extended product life.
