Technical Details & Description

1500 W peak pulse, 15.3 V standoff — the clamping decision

The 1.5KE18AHA0G: This unidirectional device is AEC-Q101 qualified, meaning it meets the automotive-grade reliability and temperature screening required for under-hood and chassis-mounted electronics. The 1500 W rating at the 10/1000 µs pulse tells you the energy it can absorb in a single surge — enough to clamp a 24 V load-dump transient on a 12 V automotive bus without the part failing short.

Housed in a DO-201AA (DO-27) axial-lead through-hole package, the part is marked with cathode band for polarity.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5KE18AHA0G in this Circuit Protection family?

The base product number 1.5KE18 covers the same 15.3 V standoff and 1500 W rating in the DO-201 package. The 'HA0G' suffix denotes the automotive AEC-Q101 qualification and tape-and-box packaging. A non-automotive variant (e.g., 1.5KE18A) shares the same electrical specs but lacks the AEC-Q101 screening.

What compliance documentation does Taiwan Semiconductor Corporation provide for 1.5KE18AHA0G?

The part is AEC-Q101 qualified, which includes the automotive stress test qualification and PPAP documentation. RoHS and REACH compliance data is available from the manufacturer's documentation set. No UL or IEC certification is listed on the record.
