1SMB170AT3G Description

Short technical summary and product information.

The 1SMB170AT3G is a 600W peak power Zener transient voltage suppressor from Littelfuse, designed to protect voltage-sensitive components from high voltage, high energy transients. It features a working peak reverse voltage of 170V, a breakdown voltage of 199V, and a maximum clamping voltage of 275V at a peak pulse current of 2.2A.

 

This unidirectional device offers fast response time of less than 1 ns and an ESD rating of Class 3 (>16 kV) per Human Body Model. It is supplied in a surface mount DO-214AA (SMB) package with corrosion-resistant, readily solderable leads and cathode polarity band marking.

 

Typical applications include communication systems, automotive electronics, numerical controls, process controls, medical equipment, business machines, and power supplies. The device is RoHS compliant and available in Pb-free finish.
