1500 W peak pulse, AEC-Q101 — what the ratings mean for the BOM
The 1.5KE12CAHE3_B/C: The clamping voltage at that current is 16.7 V maximum, meaning a 10.2 V rail sees the overvoltage clipped to 16.7 V before the surge energy dissipates — fast enough to protect downstream silicon rated for 20 V or higher. The 11.4 V minimum breakdown voltage confirms the device starts conducting before the rail reaches damaging levels. The AEC-Q101 certification means the part has passed the full suite of stress tests — temperature cycling, high-temperature reverse bias, and ESD — that the OEM PPAP auditor expects to see. Capable is not qualified; the AEC-Q101 stamp is the evidence.
