1500 W peak pulse, bidirectional, DO-201AE axial
The 1.5KE15CA_R2_00001: It clamps at 21.2 V max and handles 71 A peak pulse current — sized for protecting 12 V rails against transients like load dump or inductive kickback.
Housed in a DO-201AE axial-lead package, through-hole mount. The body is the same diameter as the common 1.5KE footprint — no surprises on the board.
Temperature range and ruggedness
No power line protection (it is a standalone TVS, not a filtered array), so it expects a clean DC rail upstream.
Marked obsolete by Panjit. If you are repairing a board that uses this part, the DO-201AE footprint is common across the 1.5KE family, so a parametric match (same standoff, same package) from another brand may fit without a layout change.
