SM8K85A

The SM8K85A is a high-power unidirectional transient voltage suppression diode rated at 8000W peak pulse power (10/1000µs), designed to protect high-voltage DC power rails from severe transient overvoltage and load dump events. Housed in a rugged DO-218AB package, it offers low leakage current, fast response time, and strong clamping capability. The device is ideal for automotive electronics, industrial control power inputs, communication infrastructure, and energy systems requiring robust surge suppression.
