The SM6T33AY is a 600W peak pulse power Zener TVS diode designed by STMicroelectronics for automotive applications. It provides unidirectional transient voltage suppression with a reverse standoff voltage of 28.2V and a maximum clamping voltage of 59V at a peak pulse current of 68A (8/20µs waveform).
This device is housed in a compact DO-214AA (SMB) surface-mount package, making it suitable for automated assembly and space-constrained designs. It operates over a wide temperature range from -55°C to 150°C, ensuring reliable performance in harsh automotive environments.
The SM6T33AY is not intended for power line protection but is optimized for signal and data line transient suppression in automotive electronics. Its Zener clamping action provides fast response to overvoltage events, protecting sensitive downstream components.
