STMicroelectronics 1-Element Bi-Directional TVS Diode 400 W, 2-Pin DO-214 SMAJ170CA-TR

STMicroelectronics SMAJ170CA-TR is a 1-Element Bi-Directional Transient Voltage Suppression (TVS) Diode with a peak pulse power dissipation rating of 400 W housed in a compact 2-pin DO-214 surface mount package. This device provides high-level transient voltage protection for electronic circuits against voltage spikes and surges commonly encountered in industrial, telecommunications, automotive (non-automotive grade), and consumer electronics applications.

Featuring a bi-directional diode configuration, it has a minimum breakdown voltage of 189 V and a maximum reverse stand-off voltage of 170 V, making it effective in clamping voltage to a safe maximum of 353 V. The device is designed to operate reliably within a temperature range of -55°C to 150°C, enabling performance stability under harsh environmental conditions.

It supports a peak pulse current of up to 6.5 A and maintains a low reverse leakage current of 1 μA, ensuring minimal impact on normal circuit operation. The compact dimensions (4.6 mm length, 2.9 mm width, 2.45 mm height) facilitate integration into space-constrained PCB designs.

The diode undergoes testing at a current of 1 mA to meet stringent quality and reliability requirements. Although it is not certified to automotive standards, its robust electrical characteristics make it suitable for industrial machinery, power supplies, telecommunications equipment, and other applications requiring reliable transient voltage suppression.
