The SMA4F170AY is a unidirectional Zener TVS diode from STMicroelectronics designed for overvoltage protection in automotive applications. It features a standoff voltage of 170V and a maximum clamping voltage of 275V, ensuring sensitive downstream components are protected from voltage transients.
With a peak pulse power rating of 400W and a peak pulse current of 1.4A, this device can handle moderate surge events. It operates over a wide temperature range of -55°C to 175°C, making it suitable for harsh automotive environments.
The SMA4F170AY is housed in a surface-mount DO-221AC (SMA Flat Leads) package, also known as SMAflat, which offers a low-profile design for space-constrained PCB layouts. It is RoHS3 compliant and has an MSL of 1 (unlimited).
