1SMB90AT3G Description

Short technical summary and product information.

The 1SMB90AT3G is a 600W unidirectional TVS diode manufactured by On Semiconductor. It is designed to protect sensitive electronics from voltage transients induced by lightning, inductive load switching, and ESD. The device offers a reverse standoff voltage of 90V and a clamping voltage of 146V at a peak pulse current of 4.1A.

 

This TVS diode is rated for a peak pulse power dissipation of 600W (10/1000µs waveform). It has a typical capacitance of 210pF at 1MHz, making it suitable for telecom applications. The operating junction temperature range is -65°C to 150°C.

 

The 1SMB90AT3G is housed in a standard DO-214AA (SMB) surface mount package, which is ideal for automated assembly. It is a Zener-type TVS diode with a single unidirectional channel. The device is RoHS3 compliant and has an MSL rating of 1 (unlimited).
