1SMB170AT3G Description

Short technical summary and product information.

The 1SMB170AT3G is a 600W peak pulse power Zener transient voltage suppressor from On Semiconductor, designed to protect sensitive electronic circuits from voltage transients. It offers a reverse standoff voltage of 170V and a maximum clamping voltage of 275V at the rated peak pulse current of 2.2A. The device features a fast response time of less than 1ns and an ESD rating of Class 3 (>16kV) per Human Body Model, ensuring robust protection against electrostatic discharge.

 

This unidirectional TVS diode is optimized for general-purpose applications, including communication systems, power supplies, automotive electronics, and industrial controls. It operates over a wide junction temperature range of -65°C to 150°C and has a typical junction-to-ambient thermal resistance of 226°C/W, which should be considered in PCB layout for effective heat dissipation.

 

The component is supplied in a surface-mount SMB (DO-214AA) package with modified L-bend leads for enhanced solder joint reliability. It is available in tape and reel packaging with a standard quantity of 2500 pieces, Pb-free and RoHS compliant (unverified).
