The SM4T47CAY is a bidirectional Zener TVS diode designed for automotive applications. It features a reverse standoff voltage of 40 V and a clamping voltage of 84 V, providing protection against transient overvoltage events.
With a peak pulse power rating of 400 W (8/20 µs waveform) and a peak pulse current capability of 27 A, this device is suitable for suppressing voltage spikes in automotive electronic systems. The Zener breakdown mechanism ensures fast response to transient threats.
The SM4T47CAY is housed in a surface-mount DO-214AC (SMA) package, enabling compact PCB layouts. It operates over a junction temperature range of -55°C to 150°C, making it robust for harsh environments. Power line protection is not provided; this device is intended for signal line protection.
