That makes it a fit for under-hood electronics, battery management, and any 12V/24V vehicle bus that sees load-dump or inductive kickback transients. ## Clamping voltage and pulse current — what they mean for your rail The 25.2 V maximum clamping voltage is the ceiling the diode holds the transient to. For a 12 V rail, this means downstream components rated at 30 V or higher have margin. The 59.5 A peak pulse current at the 10/1000 µs test waveform tells you the diode can absorb a substantial surge — think alternator load-dump or a stalled motor kickback — without failing short. The minimum breakdown voltage is 17.1 V, so the diode starts conducting between 17.1 V and the clamping voltage. That 8.1 V window between standoff and clamp gives the designer room to place the TVS after a fuse or PTC without nuisance triggering on normal switching noise. ## Package and board integration The DO-201AA (DO-27) axial leaded package is a through-hole format with a 1.5KE supplier device package code. It is a standard footprint — the leads are 0.052-inch diameter, and the body is about 9 mm long. The axial leads let you mount it standing up or lying flat, which helps with board-space constraints in dense automotive ECU layouts. Sourced through independent distribution channels.","metaTitle":"Vishay 1.5KE18CAHE3_A/D TVS Diode, 1.5kW, 15.3V, DO-201AA","metaDescription":"Vishay 1.5KE18CAHE3_A/D bidirectional TVS diode, 1500W peak pulse power, 15.3V standoff, AEC-Q101 qualified.
