SM30T33CAY Description

Short technical summary and product information.

The SM30T33CAY is a Zener TVS diode from STMicroelectronics designed for transient voltage suppression. It features a reverse standoff voltage of 28V and a clamping voltage of 45.4V at a peak pulse current of 66.1A. With a peak pulse power rating of 3000W (3kW), it provides robust protection against voltage spikes.

 

This bidirectional diode is suitable for automotive applications, operating over a temperature range of -55°C to 175°C. It is not intended for power line protection. The device is surface mounted in a DO-214AB (SMC) package, making it compatible with standard SMD assembly processes.

 

Key electrical characteristics include a single bidirectional channel and a Zener TVS construction. The part is RoHS3 compliant and REACH unaffected, though these compliance claims are unverified. The package offers a compact footprint for space-constrained designs.
