Product details

Clamping the 18V rail

The SMBJ18CA-13-F: Its 20V minimum breakdown voltage ensures the device stays off during normal operation, while the 29.2V maximum clamping voltage at 20.5A peak pulse current (10/1000µs waveform) limits the surge the downstream circuitry sees.

Package and footprint fit

Housed in a standard DO-214AA (SMB) surface-mount package, the SMBJ18CA-13-F's footprint matches the common JEDEC outline for this power class. The SMB package's copper tab on the cathode side (anode for the bidirectional structure) conducts heat into the PCB pad; the 600W rating assumes a minimum copper area per the datasheet layout recommendation. Supplied on Tape & Reel (TR) or Cut Tape (CT), the part is compatible with standard pick-and-place and reflow profiles for the DO-214AA body.
