SMBJ33CA-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 33V with a breakdown voltage range of 36.7V to 40.6V, and is rated for 600W peak power dissipation. The device exhibits typical fast response times of less than 1.0 picosecond from 0V to breakdown voltage, with a maximum clamping voltage of 53.1V at the rated current. SMBJ33CA-Q is AEC-Q101 compliant and RoHS compliant, making it suitable for automotive-grade applications. Common applications include protection of power buses, I/O interfaces, and overvoltage transient protection in telecom, computer, industrial, and consumer electronics systems.
