Automotive-grade TVS with 1.5 kW peak pulse capability
The 1.5KE82AHA0G: Its 70.1 V reverse standoff voltage and 113 V clamping point (at 13.9 A peak pulse current) suit it for protecting 48 V or 70 V DC buses in automotive electronics where a 175 °C junction temperature rating handles underhood thermal cycling without derating. Qualified to AEC-Q101 (the automotive discrete semiconductor stress-test standard), this part carries the full PPAP documentation an OEM auditor expects for production-grade safety or powertrain modules. The -55 °C to 175 °C operating temperature range covers the entire automotive temperature grade-0 envelope — a hard requirement for engine-bay or transmission-mounted electronics.
Housed in a DO-201AA (DO-27) axial-leaded package with a DO-201 supplier device code, the diode mounts through-hole — the lead bend and hole diameter follow the standard DO-201 footprint. The 1500 W pulse rating is achievable only when the leads are soldered into a copper plane that sinks the transient heat; a trace-width calculator should size the PCB landing for the 13.9 A pulse current without fusing the foil.
