The 1.5KE22A/54: A single unidirectional channel, this Zener-type TVS is suited for DC signal and power rail clamping where the circuit operates above ground. No power line protection rating — the device is intended for secondary-side signal and data-line transient suppression, not primary AC mains or high-energy power entry. The through-hole DO-201AA / DO-27 axial package suits point-to-point wiring or PCB mounting with lead forming.
The 1.5KE22A/54 is obsolete but available through independent distribution.
