Product details

1500W peak pulse, AEC-Q101, active production

The 1.5KE12CAHA0G: Its 10.2V reverse standoff voltage and 16.7V clamping at 94A peak pulse current make it suited for protecting 12V automotive and industrial supply rails from transients like load dump and inductive kickback.

Through-hole DO-201, bidirectional, no power-line protection

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE12CAHA0G is a through-hole part — hand-solderable and board-rework friendly. The 1500W rating still handles substantial surge energy for its package class.

Active lifecycle, automotive compliance, no cross-reference on record

For a BOM hedge, parametric equivalents in the 1.5KE family with the same standoff voltage and package exist, but the AEC-Q101 grade is specific to this suffix.

Frequently asked questions

What compliance documentation does Taiwan Semiconductor provide for this part?

The part carries AEC-Q101 automotive qualification, which includes stress test data and PPAP-level documentation. Standard RoHS and REACH compliance is typical for Taiwan Semiconductor's 1.5KE series, though specific certificates should be confirmed at RFQ.
