SMBJ12CA TVS Diode – 12V Bidirectional Transient Suppressor (SMB Package)

Product Description:
The SMBJ12CA TVS Diode is a high-performance bidirectional transient voltage suppressor engineered to protect 12V-powered sensitive electronic circuits from transient events such as lightning surges, ESD, and inductive load switching. With a reverse stand-off voltage of 12V, a minimum breakdown voltage of 13.3V, and a clamping voltage of 19.9V, this diode provides strong and fast protection for power lines, I/O interfaces, and critical components.

Housed in a compact SMB (DO-214AA) surface-mount package, the SMBJ12CA offers 600W peak pulse power capability, a peak pulse current of 30.2A, and an ultra-fast response time. The glass-passivated junction, low incremental surge resistance, and AEC-Q101 qualification availability ensure exceptional reliability for industrial, telecom, embedded, and automotive applications.

This TVS diode is optimized for automated SMT assembly and provides dependable protection for circuits that require stable and efficient overvoltage suppression.
