SUNMATE Elec · ESD And Surge Protection (TVS/ESD) · DO-27
1.5KE24A 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, the end marked with the cathode band on this unidirectional 1.5KE24A; it is the positive side in reverse breakdown (VBR 22.8-25.2 V at 1.0 mA, VRWM 20.5 V, VC 33.2 V at 45.8 A). |
| 2 | A | passive | Anode, the axial lead at the end without the cathode band; the datasheet rates peak pulse power at 1500 W minimum (10/1000µs) and peak forward surge current at 200 A. |
