The SMA6J8.5A-TR is a unidirectional Zener TVS diode from STMicroelectronics designed for general purpose transient voltage suppression. It features a reverse standoff voltage of 8.5V and a maximum clamping voltage of 18.7V at a peak pulse current of 205A (8/20µs waveform). The device can handle 600W of peak pulse power, making it suitable for protecting sensitive electronics from voltage spikes.
This TVS diode is housed in a surface-mount DO-214AC (SMA) package, enabling compact PCB designs and compatibility with automated assembly processes. It operates over a wide temperature range of -55°C to 175°C (junction temperature). The component is unidirectional with one channel and is not intended for power line protection.
Typical applications include general purpose circuit protection in consumer, industrial, and automotive electronics where reliable clamping of transient overvoltages is required. The SMA6J8.5A-TR is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
