The 1.5KE75A-G comes in a DO-201AA, DO-27, Axial through-hole package (supplier device package DO-201) — the lead bend and body length match the standard 1.5KE series footprint, so a board already laid out for a DO-201 TVS accepts this part without a pad spin.
Clamping and breakdown parametrics
Reverse standoff voltage is 64.1V typ — the device stays high-impedance below that rail, so a 48V or 60V DC bus sees no leakage until the transient pushes past the standoff threshold. Breakdown voltage min is 71.25V, clamping max at 103V across the 14.56A peak pulse current — the 32V clamping window between breakdown and clamp means the protected node sees a hard voltage ceiling during the surge event.
