Part of the Automotive, AEC-Q101 qualified TransZorb series, it is designed for transient protection in automotive electronics — engine control units, infotainment, and body controllers that see load-dump and inductive-switching spikes. Vishay lists this part as obsolete. ## Clamping voltage and pulse capability The 104 V clamping voltage at 14.6 A peak pulse current defines the protection ceiling — any downstream circuitry must survive that voltage for the 10/1000 µs pulse duration. The 64.1 V standoff means the diode stays transparent on a nominal 48 V or 60 V bus, only clamping when the transient exceeds the breakdown threshold.","metaTitle":"1.5KE75CAHE3/51 TVS Diode, 1500W, 64.1V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE75CAHE3/51 bidirectional TVS, 1500W peak pulse, 64.1V standoff, AEC-Q101.
