SM30T47CAY Description

Short technical summary and product information.

The SM30T47CAY is a 3000W (3kW) peak pulse power Zener TVS diode designed for automotive applications. It features a reverse standoff voltage of 40V and a clamping voltage of 64.5V, with a peak pulse current rating of 43.5A. This unidirectional device is housed in a surface-mount DO-214AB (SMC) package and operates over a temperature range of -55°C to 175°C.

 

As an automotive-grade component, the SM30T47CAY is suitable for protecting sensitive electronics from voltage transients in harsh environments. The DO-214AB package offers a compact footprint for space-constrained designs while providing robust power handling capability.

 

Key specifications include a 3kW peak pulse power rating, 40V reverse standoff voltage, and 64.5V clamping voltage. The device is surface-mountable and does not provide power line protection.
