SM30T56CAY Description

Short technical summary and product information.

The SM30T56CAY is a bidirectional TVS (Transient Voltage Suppression) diode designed for automotive applications. It provides protection against voltage transients with a reverse standoff voltage of 48V and a minimum breakdown voltage of 53.3V. The clamping voltage is 76.6V at a peak pulse current of 38A (10/1000µs waveform). With a peak pulse power rating of 3000W (3kW), it can handle high energy transients.

 

This device is intended for power line transient protection and is suitable for use in automotive electronics where robust transient suppression is required. The SMC package (DO-214AB) is a surface-mount package, enabling automated assembly. The operating temperature range is -55°C to 175°C, making it suitable for harsh environments.

 

The SM30T56CAY is a single bidirectional channel device, offering protection for both positive and negative transients. It is listed as RoHS3 compliant, MSL level 1 (unlimited), and REACH unaffected.
