With a 7.7 V reverse standoff voltage and a minimum breakdown of 8.65 V, it clamps transients at 13.4 V (max) while conducting 117 A peak pulse current. The 1.5 kW rating means it absorbs a 10/1000 µs surge without exceeding the junction temperature limit — sized for secondary protection on 12 V automotive buses where load-dump and inductive kickback are routine. ## Single-channel bidirectional layout in DO-201AA axial This is a single-channel bidirectional device — the breakdown characteristic is symmetrical, so no polarity concern during board assembly. The DO-201AA (DO-27) axial leaded package is through-hole mounted, suited for point-to-point wiring or PCB insertion where the leads are bent and soldered. The 1.5KE supplier device package footprint is standard across the series. It carries no power line protection rating, meaning it is intended for signal or low-side DC rail clamping, not mains AC. The Telecom application tag confirms the 10/1000 µs pulse shape matches Telcordia GR-1089 surge requirements — common in base-station power feeds and 48 V telecom rectifiers. ## Active production — sourced per RFQ Listed as Active on the manufacturer's lifecycle record.","metaTitle":"1.5KE9.1CAHE3_B/C Vishay TVS Diode, 1500W, AEC-Q101","metaDescription":"Vishay 1.5KE9.1CAHE3_B/C TransZorb TVS diode, 1500W peak pulse, 7.7V standoff, bidirectional, AEC-Q101 qualified.
