1SMA36AT3G Description

Short technical summary and product information.

The Littelfuse 1SMA36AT3G is a 400W unidirectional TVS diode designed to protect sensitive electronic circuits from high voltage transients. It features a working peak reverse voltage of 36V and a clamping voltage of 58.1V at a peak pulse current of 6.9A. The device uses a Zener breakdown mechanism and provides a fast response time of less than 1 ns to transient events.

 

This TVS diode is offered in the compact, surface mount DO-214AC (SMA) package, making it suitable for automated assembly. It supports an operating temperature range of -65°C to 150°C and has an ESD rating greater than 16 kV per the Human Body Model. The part is Pb-free and designed for general purpose applications such as power supplies, communication systems, and industrial controls.

 

With 400W peak power dissipation capability and a forward surge current rating of 40A, the 1SMA36AT3G provides robust transient protection. The single unidirectional channel is ideal for DC voltage rail clamping. Designers should verify breakdown voltage and leakage current from the specific device datasheet for precise circuit design.
