1.5 kW peak pulse, 12.8 V standoff — what the ratings mean for the BOM
The 1.5KE15A_R2_00001: The 12.8 V reverse standoff voltage defines the maximum continuous DC voltage the protected line can carry without the diode conducting leakage — a 12 V rail with tolerance up to 12.8 V is within the safe window. When a transient exceeds the 14.3 V minimum breakdown threshold, the diode clamps at 21.2 V maximum, shunting up to 71 A of surge current away from the downstream circuitry.
DO-201AE axial — through-hole footprint and board integration
Housed in the DO-201AE axial-lead package, this TVS mounts through-hole on a PCB or terminal block. The 0.052-inch (1.3 mm) lead diameter fits standard plated-through holes, and the body length of about 7.5 mm allows manual or wave-solder assembly.
Obsolete — sourcing through surplus and broker channels
Panjit has marked the 1.5KE15A_R2_00001 as obsolete. No official successor order code is listed by the manufacturer. Availability and pricing are confirmed at RFQ against the specific quantity and date-code requirements.
