SMAJ8.5A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in portable communications, computing, and video equipment. It features a compact DO-214AC (SMA) surface mount package with a maximum reverse voltage rating of 8.5 V and a breakdown voltage of 9.44 V. The device delivers 400 watts peak power dissipation with typical response times less than 1.0 nanosecond, providing fast transient suppression. With lead-free, RoHS-compliant construction, the SMAJ8.5A is ideal for protecting sensitive circuits in modern electronic applications requiring reliable overvoltage protection in minimal board space.
