The SM4T56CAY is a bidirectional Zener TVS diode from STMicroelectronics, designed for automotive applications requiring transient voltage protection. It features a reverse standoff voltage of 48V, a minimum breakdown voltage of 56V, and a maximum clamping voltage of 100V at a peak pulse current of 23A (8/20µs waveform). The device can handle 400W peak pulse power under a 10/1000µs waveform.
This TVS diode is suitable for protecting sensitive electronic circuits in automotive systems from voltage transients. It is not intended for power line protection. The operating junction temperature range spans from -55°C to 150°C, ensuring reliable performance across harsh environments.
The SM4T56CAY is offered in a surface mount DO-214AC (SMA) package, enabling compact PCB designs and automated assembly processes. The package is also known as SMA (DO-214AC).
