The SM4T33AY is a unidirectional Zener TVS diode designed for automotive applications. It features a reverse standoff voltage of 28 V and a minimum breakdown voltage of 31.1 V. The device clamps transient overvoltages at a maximum of 59 V while handling peak pulse currents up to 39 A (8/20 µs waveform).
With a peak pulse power rating of 400 W, this diode provides robust protection against voltage transients in automotive electronic systems. It is not intended for power line protection, making it suitable for signal and data line applications.
The SM4T33AY is housed in a DO-214AC (SMA) surface-mount package and operates over a junction temperature range of -55°C to 150°C. Its compact SMA footprint enables high-density PCB layouts in space-constrained automotive modules.
