The SMA6T28AY is a 600W unidirectional transient voltage suppression (TVS) diode designed by STMicroelectronics for automotive applications. It features a reverse standoff voltage of 24V and a clamping voltage of 44.3V at a peak pulse current of 80A (8/20µs waveform). The device is built using Zener technology and provides no power line protection, making it suitable for signal line protection.
This TVS diode is housed in a DO-214AC (SMA) surface-mount package with an operating junction temperature range of -40°C to 150°C. The SMA package is widely used for automated assembly and offers a compact footprint for space-constrained designs.
With its automotive-grade rating, the SMA6T28AY is intended for use in vehicle electronics where transient overvoltage protection is required. The 600W peak pulse power capability ensures robust protection against voltage spikes in 24V nominal systems.
