Vishay Uni-Directional TVS Diode 400 W, 2-Pin Surface Mount DO-214 Package SMAJ40A-E3/61

Vishay SMAJ40A-E3/61 is a uni-directional transient voltage suppressor (TVS) diode offering 400 W peak pulse power dissipation. Packaged in a rugged surface mount DO-214 package with 2 pins, this diode is engineered to protect sensitive electronic circuits against voltage transients caused by inductive load switching and lightning surges.

Its minimum breakdown voltage is 44.4 V with a maximum reverse stand-off voltage of 40 V and clamping voltage of 64.5 V. This robust clamping capability safeguards devices by clamping voltage spikes within safe limits. The device features a test current of 1 mA and can handle peak pulse currents up to 6.2 A, providing effective transient energy absorption.

Designed for harsh industrial and automotive environments, the SMAJ40A-E3/61 can operate reliably from -55°C to 150°C and meets the AEC-Q101 automotive quality standard. Its very low maximum reverse leakage current of 1 μA ensures minimal power loss and high energy efficiency.

This transient voltage suppressor is ideal for electronic systems in automotive, industrial machinery, telecommunications, consumer electronics, and power supply equipment. The compact DO-214 surface mount package (4.5 mm length x 2.79 mm width x 2.087 mm height) enables efficient board space utilization in high-density PCB assemblies.

Vishay's TRANSZORB TVS series guarantees premium quality and long-term reliability in industrial and automotive applications. These diodes protect circuit components from destructive transient voltages and electrostatic discharge (ESD) events.
