Product details

Peak pulse power and clamping — the numbers that decide the protection level

The 1.5KE27CA/B: The 23.1 V reverse standoff voltage is the DC or peak-AC line voltage the TVS blocks without conducting; the breakdown starts at 25.7 V minimum. For a 24 V nominal rail, this standoff gives margin above the normal operating level so the diode stays off until a transient arrives.

Package and mounting — through-hole axial for board-level retrofits

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE27CA/B mounts through-hole. The axial leads suit point-to-point wiring or PCB insertion where the lead bend radius and hole diameter match the standard DO-201 footprint.
