AEC-Q101 qualification and 1500 W pulse rating
The 1.5KE13AHA0G is a Zener TVS diode from the 1.5KE series, carrying AEC-Q101 automotive qualification — the stress and reliability screening required for ECU, sensor, and actuator protection circuits in under-hood and cabin environments. The 12.4 V minimum breakdown voltage ensures the device stays off the rail under nominal 12 V system conditions, only conducting when a surge exceeds the threshold.
Supplied in a DO-201AA / DO-27 axial-lead through-hole package (supplier device package DO-201). The axial body and 0.042-inch lead diameter suit hand-insertion or wave-solder assembly; the lead bend radius must be kept above 1.5 mm to avoid stress cracks at the glass seal. Packaged in Tape & Box (TB) — not tape-and-reel, so pick-and-place requires a tube feeder or manual placement. The TB format is common for axial parts in low-to-medium volume builds.
No pin-compatible second source or successor is listed in the official documentation. The base product number 1.5KE13 covers the non-automotive variant; the A0G suffix denotes the AEC-Q101 qualified version with the automotive-grade screening.
