1500W surge clamp for a 10V rail
The 1.5SMC10CAHR7G: That means a 10V supply rail exposed to a surge gets clipped at 14.5V — well within the typical 20V abs-max of downstream 12V-rated ICs. The reverse standoff voltage is 8.55V, so the diode stays off below that threshold and only conducts during a transient. It is not rated for power-line protection — the unidirectional clamping characteristic and 108A pulse current suit signal or low-power bus clamping.
AEC-Q101 grade and temperature envelope
This part carries AEC-Q101 qualification, the automotive discrete semiconductor stress test that covers temperature cycling, high-temperature reverse bias, and ESD robustness. The operating junction temperature range is -55°C to 150°C, which matches the under-hood or engine-bay ambient where 125°C air temperatures are common and the die self-heats during a pulse. The 1.5SMC series includes other voltage grades; this variant is the 10V bidirectional option with the 'C' suffix indicating a 5% tolerance on breakdown.
DO-214AB (SMC) board-fit
Housed in the DO-214AB (SMC) package, a surface-mount footprint with a 7.9 mm body length and 6.8 mm width. The cathode tab is the larger pad for heat sinking — the 1500W pulse rating assumes a standard copper land pattern on the PCB. Reflow profile follows standard Sn-Pb or Pb-free solder profiles; no special bake required if stored in moisture-barrier bags per J-STD-020.
