1SMC40AT3G Description

Short technical summary and product information.

The 1SMC40AT3G is a 1500W unidirectional Zener TVS diode manufactured by On Semiconductor. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.

 

Key electrical specifications include a reverse standoff voltage of 40V, a maximum clamping voltage of 64.5V at a peak pulse current of 32.2A (10/1000µs waveform), and a peak pulse power rating of 1500W. The device is not intended for power line protection and is rated for general purpose applications.

 

The diode is housed in a DO-214AB (SMC) surface-mount package, suitable for automated assembly. It operates over a junction temperature range of -65°C to 150°C, making it suitable for a wide range of environments.
