SMBJ26A-Q is a transient voltage suppressor diode designed for surge and ESD protection applications in compact DO-214AA (SMB) surface mount package. It features a working peak reverse voltage (VRWM) of 26V with a breakdown voltage range of 28.9V to 31.9V, providing reliable overvoltage transient protection. The device delivers 600 watts peak power dissipation with typical fast response times of less than 1.0 picosecond from 0V to breakdown voltage, and includes a maximum clamping voltage of 42.1V at 10A. This automotive-grade, AEC-Q101 compliant, RoHS-compliant device is ideal for protecting power buses, I/O interfaces, and various telecom, computer, industrial, and consumer electronics applications requiring robust transient protection.
