The junction temperature range spans -55 °C to 175 °C — wide enough for under-hood placement where ambient heat and self-heating from repetitive surges stack. No power-line protection feature is built in — this is a pure transient suppressor, not a voltage regulator. The TransZorb series has broad second-source coverage in the 1500 W axial footprint, but no official pin-compatible alternative is listed by Vishay for this exact order code.","metaTitle":"Vishay 1.5KE12CAHE3_A/C TVS Diode, 1500W, 10.2V, DO-201AA","metaDescription":"Vishay 1.5KE12CAHE3_A/C bidirectional TVS diode, 1500W peak pulse power, 10.2V reverse standoff, AEC-Q101 automotive grade.
