1SMC70AT3G Description

Short technical summary and product information.

The 1SMC70AT3G is a unidirectional Zener transient voltage suppression (TVS) diode from On Semiconductor designed for general purpose circuit protection. It features a reverse standoff voltage of 70V and a clamping voltage of 113V at a peak pulse current of 13.3A, delivering 1500W of peak pulse power.

 

This device is housed in a surface mount DO-214AB (SMC) package and operates over a wide temperature range of -65°C to 150°C. It is suitable for applications requiring protection against voltage transients in power supplies, industrial equipment, and telecommunications systems.

 

The TVS diode is RoHS compliant and has a moisture sensitivity level of 1 (unlimited). It is not designed for power line protection, making it ideal for low-voltage signal and DC power bus protection.
