Vishay 1-Element Uni-Directional Transient Voltage Suppressor TVS Diode 400 W, 2-Pin DO-214 SMAJ33A-E3/61

Vishay SMAJ33A-E3/61 is a 1-element uni-directional transient voltage suppressor (TVS) diode designed for efficient voltage spike protection in electronic circuits. It features a peak pulse power dissipation rating of 400 watts, housed in a compact DO-214 surface mount package with 2 pins, facilitating easy integration into modern electronic assemblies.

With a minimum breakdown voltage (Vbr) of 36.7 V and a clamping voltage (Vc) of 53.3 V, this diode effectively clamps voltage surges, thereby safeguarding sensitive semiconductor devices. Its maximum reverse stand-off voltage (Vwm) is 33 V, making it suitable for circuits operating near this voltage level.

The device offers a wide operational temperature range from -55°C up to a maximum of 150°C, ensuring reliable performance in demanding industrial, automotive, and power electronics environments. Additionally, the diode meets the stringent AEC-Q101 automotive standard, affirming its suitability for automotive electronics applications.

Its small form factor dimensions of 4.5 mm length, 2.79 mm width, and 2.09 mm height make it ideal for compact PCBs, maintaining space efficiency. The device supports electrostatic discharge (ESD) protection with a maximum peak pulse current of 7.5 A and a minimal reverse leakage current of 1 μA, contributing to enhanced circuit robustness.

This TVS diode is commonly deployed in applications including industrial control systems, power supplies, automotive electronics, communication equipment, and other environments requiring transient over-voltage protection. Its robust design ensures long service life and dependable operation in critical scenarios.
