What the 1500W rating means for your protection design
The 1.5KE24A-TP: The clamping voltage at peak pulse current is 33.2 V max, so a 24 V nominal rail (20.5 V reverse standoff) sees the clamp engage at roughly 33 V, protecting downstream silicon rated for 36 V or higher. The reverse standoff voltage of 20.5 V means the diode draws negligible leakage below that level — it sits across the rail without loading it. Breakdown starts at 22.8 V min, giving a 2.3 V window before the clamp fully conducts. This is a standard 24 V system protection part for industrial control, telecom, and automotive auxiliary rails.
Package, temperature range, and board integration
Housed in a DO-201AE axial-lead package, the 1.5KE24A-TP is a through-hole part suited for point-to-point wiring or PCB mounting with 0.042-inch diameter leads. The part is unidirectional — the cathode band marks the anode-to-ground orientation for positive transient clamping.
Lifecycle and supply posture
Micro Commercial Co lists the 1.5KE24A-TP as Active. It is available in Tape & Reel (TR) or Cut Tape (CT) packaging for the DO-201AE axial format. Sourced through independent distribution — confirmed pricing and lead time against an RFQ.
