Product details

TransZorb® TVS — 1500 W peak pulse, bidirectional

The 1.5KE22CA-E3/54: The breakdown voltage range starts at 20.9 V minimum, so the diode stays out of conduction below the normal bus voltage and only clamps when a spike exceeds the threshold.

DO-201AA axial — rework-friendly through-hole

Supplied in tape and reel (TR) or cut tape (CT) options, the axial format suits hand-insertion or wave-solder assembly. No special reflow profile needed; the leads absorb the heat before the junction sees it.

Sourcing and compliance

No pin-compatible alternative is documented in this listing. The base product number 1.5KE22 covers unidirectional and bidirectional variants; the -/54 suffix indicates the lead-free, RoHS-compliant finish in tape-and-reel packaging.
