SM30T30CAY Description

Short technical summary and product information.

The SM30T30CAY is a bidirectional Zener TVS diode from STMicroelectronics designed for automotive applications. It provides transient voltage protection with a reverse standoff voltage of 26V and a clamping voltage of 42.1V. The device can handle peak pulse currents up to 71.3A with a peak pulse power rating of 3000W (3kW).

 

This TVS diode is configured as a single bidirectional channel, making it suitable for protecting sensitive circuits from voltage transients in both directions. It is not intended for power line protection, as indicated by the 'No' value for power line protection specification.

 

The SM30T30CAY is housed in a surface-mount DO-214AB (SMC) package and is rated for operation over a wide temperature range of -55°C to 175°C. It is built for automotive environments, ensuring reliable performance under harsh conditions.
