Breakdown starts at 44.7 V min, and clamping is hard-limited to 64.8 V at 23.1 A peak pulse current. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE47CAHE3_A/D mounts with standard 0.040-inch diameter holes. The bidirectional configuration uses a single device for both positive and negative transients — one part covers both polarities, saving board space over a back-to-back pair.","metaTitle":"Vishay 1.5KE47CAHE3_A/D TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE47CAHE3_A/D TransZorb TVS diode, 1500W peak pulse, 40.2V standoff, AEC-Q101 automotive grade.
