1.5KE30A

SUNMATE Elec · ESD And Surge Protection (TVS/ESD) · DO-27

1.5KE30A from SUNMATE Elec, in a DO-27. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, marked by the cathode band on the unidirectional 1.5KE30A; positive terminal in reverse standoff (VRWM 25.6 V, VBR 28.5-31.5 V at 1.0 mA, max clamping 41.4 V at IPP 36.7 A).
2 A passive Anode, the unbanded axial lead of the unidirectional 1.5KE30A; 1500 W minimum peak pulse power (10/1000 µs) with 200 A peak forward surge current.
