SMAJ24CA-Q is a bidirectional transient voltage suppressor (TVS) diode designed for surge and ESD protection applications. It features a working peak reverse voltage of 24 V, breakdown voltage range of 26.7 V to 29.5 V, and maximum clamping voltage of 38.9 V at 10.3 A. The device offers 400 W peak pulse power dissipation at 1 ms pulse width, with fast response times less than 1.0 picosecond from 0 V to breakdown voltage. Housed in a compact DO-214AC (SMA) surface mount package, it operates over a temperature range of -55°C to +150°C and is both RoHS and AEC-Q101 compliant. Common applications include protection of power buses, I/O interfaces, and overvoltage transient protection in automotive, telecom, computer, industrial, and consumer electronics.
