Product details

Obsolete — sourcing through independent channels

The 1.5KE27CA-B is classified as Obsolete by Diodes Incorporated, meaning the original manufacturer no longer produces it. Sourcing is through independent distribution, with availability and pricing confirmed per RFQ.

The 23.1 V reverse standoff voltage means the protected rail can run at up to 23.1 V DC without the diode conducting leakage. Breakdown occurs at 25.7 V minimum, so the diode starts clamping before the rail exceeds the safe operating area of downstream 24 V-rated ICs. Single bidirectional channel handles both positive and negative transients on the same line.

Package and board integration

Supplied in a DO-201AA / DO-27 axial-lead package (DO-201 supplier device package), through-hole mount. The bulk packaging suits manual insertion or low-volume rework; no tape-and-reel for automated pick-and-place.
