1500W peak pulse, AEC-Q101 qualified
The 1.5SMC15AHE3/57T: It clamps a 12.8V reverse standoff voltage to 21.2V maximum at 70.8A peak pulse current, protecting downstream electronics from transients up to that energy level. The -65°C to 150°C junction temperature range covers under-hood thermal extremes.
DO-214AB SMC package and board integration
Housed in a DO-214AB (SMC) surface-mount package, the device footprint matches the industry-standard SMCJ outline. The large copper tab on the cathode side conducts heat to the PCB copper plane — the junction-to-ambient thermal resistance depends on the pad area, so a 1-inch² copper land is recommended for full 1500W pulse capability. The base product number is 1.5SMC15, so the same die is available in other package or lead-free variants under that base.
