SMBJ26CA-Q is a bidirectional 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, breakdown voltage range of 28.9V to 31.9V, and maximum clamping voltage of 42.1V at 10A reverse leakage current. The device delivers 600W peak power dissipation capability with typical response times less than 1.0 picosecond from 0V to breakdown voltage, and is AEC-Q101 compliant for automotive applications. SMBJ26CA-Q is ideal for protecting power buses, I/O interfaces, and various telecom, computer, industrial, and consumer electronics applications requiring reliable transient protection.
