Clamping voltage and peak pulse current
The 1.5SMC15CA-M3/9AT: Its 12.8V reverse standoff voltage means it begins conducting at 14.3V breakdown (minimum) and clamps transients to 21.2V maximum at the rated 70.8A peak pulse current.
Active status and BOM fit
The bidirectional channel protects against both positive and negative transients on a single device, reducing component count on the rail.
Package and temperature range
Housed in a DO-214AB (SMC) surface-mount package, the device operates across -65°C to 150°C junction temperature. The wide temperature grade suits outdoor or industrial equipment where the ambient sees extremes, and the SMC footprint provides adequate copper area for heat sinking the 1500W pulse without exceeding the junction limit.
