1500W peak pulse — what it means for a 13.6V rail
The 1.5KE16CAHE3_A/C: It clamps at 22.5V max when the surge current reaches 66.7A, protecting a 13.6V nominal rail from transients that would otherwise exceed the downstream IC's absolute maximum. The standoff voltage of 13.6V means the diode draws negligible leakage at the normal operating voltage, while the minimum breakdown of 15.2V ensures it triggers before the rail rises into damage territory. This window suits 12V automotive battery lines, where load-dump and alternator field-decay transients can hit 30V or more.
Automotive grade and temperature envelope
It is rated for the full 1500W pulse without derating up to 25°C; above that, follow the power-derating curve in the datasheet. The axial leads suit point-to-point wiring or PCB mounting with 0.040-inch diameter holes.
