1500 W surge clamp in an axial-lead body
The 1.5KE27CA-E3/73: Its reverse standoff voltage is 23.1 V, breakdown starts at 25.7 V minimum, and clamping is held to 37.5 V at the 40 A peak pulse current — a tight window that keeps downstream silicon inside its safe operating area.
Through-hole package that survives the rework station
Housed in a DO-201AA (DO-27) axial-lead through-hole package, this part is built for boards where reliability trumps density — the leads take a soldering iron or wave solder without the thermal stress a surface-mount part sees under hot air. It is a single bidirectional channel — one device clamps both polarities, saving a diode bridge and a second part on the rail.
