Transient suppression for 12V rails
The 1.5SMC13CA_R1_00001: That 82 A figure is the current the diode shunts during the surge — the clamping voltage times that current gives the power the device absorbs, and the 1500 W rating confirms it survives that stress without failing short.
Package and board integration
Housed in a DO-214AB (SMC) surface-mount package, the part's footprint matches the standard SMC land pattern. The wide tab on the cathode side (marked by the band) carries the heat into the PCB copper — for sustained repetitive surges, the board's copper area under the tab sets the thermal impedance, not the package alone. Operating temperature range spans -55°C to 150°C junction, covering automotive under-hood and industrial enclosure ambient conditions.
Sourcing and compliance
No official pin-compatible second source or successor is listed on the manufacturer's record. The 1.5SMC series includes other voltage variants with the same package and footprint; a BOM change to a different standoff voltage would require re-evaluating the protection threshold.
