The SM4T56AY is a unidirectional TVS diode from STMicroelectronics designed for circuit protection in automotive applications. It features a Zener technology with a standoff voltage of 48V and a clamping voltage of 100V. The device can handle a peak pulse current of 23A under an 8/20µs waveform and a peak pulse power of 400W. It operates over a junction temperature range of -55°C to 150°C. The SM4T56AY is surface mountable in a DO-214AC (SMA) package, making it suitable for space-constrained designs. It is RoHS3 compliant and has an MSL of 1 (unlimited). Note that power line protection is not provided. The part is intended for automotive electronics requiring transient voltage suppression.
