1500 W surge clamp for 18.8 V rails
The 1.5KE22CAHE3_A/C: The 20.9 V minimum breakdown voltage ensures the device starts conducting before the downstream circuitry sees damaging overvoltage. The single bidirectional channel means it clamps both positive and negative surges with one device, saving board space and bill-of-materials count.
AEC-Q101 automotive grade
Qualified to AEC-Q101, this part is screened for automotive reliability — temperature cycling, high-temperature reverse bias, and ESD robustness per the standard. The DO-201AA (DO-27) axial through-hole package suits high-reliability point-to-point wiring or PCB mounting where a robust mechanical anchor is needed. The leaded format also simplifies manual replacement in rework or field repair scenarios.
