Product details

Obsolete — last-time-buy window closed

The 1.5KE22CA-B: The last-time-buy period has passed — new production is not available from the factory. Sourcing now runs through independent surplus and broker channels.

1500 W peak pulse — 30.6 V clamp ceiling

Bidirectional single-channel design — one device protects both polarities, simplifying board layout on AC-coupled or bipolar signal lines.

DO-201 axial — through-hole, wide temp range

Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the part mounts through-hole and suits point-to-point wiring or PCB layouts where a surface-mount TVS is not preferred. Supplied in bulk packaging — no tape-and-reel, so the procurement quantity is not constrained by reel minimums.

Frequently asked questions

How do I get current pricing and availability for the 1.5KE22CA-B?

Submit an RFQ against your BOM quantity.

What is the closest pin-compatible alternative to the 1.5KE22CA-B?

For a functional replacement, look for a bidirectional TVS in a DO-201 axial package with a 1500 W peak pulse rating and an 18.8 V reverse standoff — the clamping voltage and breakdown window should match the original BOM position. Confirm the replacement's Ipp rating at the same 10/1000 µs waveform before committing.
