1.5KE12A 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 (unidirectional 1.5KE12A); reverse stand-off voltage VRWM 10.2 V, breakdown 11.4-12.6 V at 1.0 mA, max clamping 16.7 V at 91.0 A peak pulse current. |
| 2 | A | passive | Anode, the lead opposite the cathode band; peak pulse power 1500 W minimum (10/1000µs) and operating temperature -65 to +175 °C. |
