Protection envelope — 1500 W in a DO-201
The 1.5KE130CA B0G: That 1.5 kW rating means it absorbs a transient without letting the clamped voltage exceed 179 V — the voltage your downstream silicon sees. Reverse standoff is 111 V, so a 100 V rail sits comfortably below the leakage knee. Breakdown starts at 124 V minimum, and the clamping voltage at 8.7 A peak pulse current is 179 V max — that 55 V window between standoff and clamp is the headroom the TVS gives the protected circuit before it folds back.
Package and board fit
Through-hole axial-lead package in DO-201AA (DO-27) outline, supplied in bulk. The DO-201 body is the standard footprint for 1.5 kW TVS diodes — it fits existing PCB layouts across the 1.5KE family without a pad revision.
Taiwan Semiconductor lists the 1.5KE130CA B0G as active.
