STMicroelectronics TVS Diode Uni-Directional 400 W 2-Pin DO-214 SMAJ40A-TR

STMicroelectronics SMAJ40A-TR is a reliable 1-element uni-directional TVS diode with a peak pulse power rating of 400 W designed for surface mount technology in electronic circuits. Packaged in a compact 2-pin DO-214 case, this diode configuration offers effective transient voltage suppression to safeguard sensitive components against voltage spikes and surges.

The device provides a minimum breakdown voltage of 44.4 V and a maximum clamping voltage of 84 V, ensuring rapid response to transient events while maintaining circuit stability. Its maximum reverse stand-off voltage is 40 V, allowing normal operation under steady conditions. With a maximum peak pulse current capability of 27 A, it can handle substantial surge currents without damage.

The SMAJ40A-TR operates across a wide temperature range from -55°C to 150°C, making it suitable for industrial, commercial, and consumer electronic applications operating under diverse environmental conditions. The DO-214 package dimensions include a length of 4.6 mm, width of 2.9 mm, and height of 2.25 mm, providing a compact footprint for dense PCB layouts.

This TVS diode exhibits a minimal maximum reverse leakage current of 1 μA, thereby reducing power dissipation and enhancing system efficiency. It is part of the SMAJxxA series, optimized for providing transient voltage suppression in electronic and electrical equipment to improve reliability and prolong component life. Notably, it does not meet automotive grade standards and should be used accordingly.

This diode finds extensive use in industrial electronics, power supply circuits, telecommunications, data communication lines, and control modules to protect against voltage transients caused by inductive load switching, lightning, or electrostatic discharge. It is ideal for manufacturing and repair settings requiring durable and effective ESD protection.
