The junction temperature range spans -55°C to 175°C, covering the full automotive under-hood ambient plus self-heating margin during a transient. The bidirectional configuration (single channel) protects signal or power lines that swing both polarities, eliminating the need for two series diodes. ## Active Production and Sourcing Posture The base product number is 1.5KE56 — the full suffix (CAHE3_A/D) encodes the bidirectional polarity, AEC-Q101 qualification, and packaging (Tape & Box).","metaTitle":"1.5KE56CAHE3_A/D Vishay TVS, 1.5kW, 77V Clamp, AEC-Q101","metaDescription":"Vishay 1.5KE56CAHE3_A/D bidirectional TVS diode, 1500W peak pulse, 77V clamp, AEC-Q101 qualified.
