The 1.5KE51C: The reverse standoff voltage is 43.6 V — the line sits here under normal operation without the diode conducting. That 30 V window between standoff and clamp gives the downstream circuitry a defined survival envelope.
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE51C is a through-hole part suited for point-to-point wiring or PCB mounting with plated through-holes.
