Product details

1.5KE33A-TP protection envelope

It is unidirectional, so it protects one polarity — the cathode band goes toward the rail, anode to ground. That 17.5V window between standoff and clamp gives enough headroom for a regulated 24V bus to ride through surges without nuisance triggering.

Active production — no end-of-life signal

Micro Commercial Co lists the 1.5KE33A-TP as Active. The DO-201AE axial package is a through-hole form factor that suits point-to-point wiring on terminal blocks, breadboards, or retrofit into legacy PCB layouts.
