Vishay TRANSZORB TVS Diode 1-Element Bi-Directional 1.5 kW Surface Mount DO-214 2-Pin SMCJ170CA-E3/57T

Vishay SMCJ170CA-E3/57T is a TRANSZORB® series Transient Voltage Suppressor (TVS) diode designed for surface mount applications with a DO-214 package. It provides a high peak pulse power dissipation of 1.5 kW and features a bi-directional diode configuration capable of protecting electronic circuits against transient voltage spikes in both polarities.

This TVS diode is suitable for diverse industrial and automotive uses thanks to its compliance with the rigorous AEC-Q101 automotive standard. Its robust design supports high surge currents with a maximum peak pulse current rating of 5.5 A, efficiently shunting transients while maintaining low leakage current of 1 μA to minimize power losses.

The device operates over a wide temperature range from -55°C to 150°C, making it reliable for harsh environments encountered in manufacturing, automotive electronics, and industrial controls. The compact DO-214 surface mount package measures 7.11 mm in length, 6.22 mm in width, and 2.42 mm in height, facilitating integration into space-constrained PCB designs.

With a minimum breakdown voltage of 189 V and a maximum reverse stand-off voltage of 170 V, this diode assures strong protection by clamping transients to 275 V. Its single-element per chip configuration simplifies circuit design while ensuring dependable protection performance.

This bi-directional TVS diode is employed extensively in protecting power supplies, communication lines, and sensitive semiconductor components from damaging voltage surges caused by switching transients, electrostatic discharge (ESD), and lightning strikes.

Designed for surface mount with DO-214 package for efficient PCB assembly and manufacturing. Bi-directional configuration protects circuits from both positive and negative transient voltage spikes. High peak pulse power rating of 1.5 kW for robust transient suppression in demanding environments.
