KSMAJ14A-E3 from KUU, in a SMA. 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 color band on the unidirectional KSMAJ14A; connect to the protected line (VRWM 14 V, breakdown 15.60-17.20 V at 1 mA, clamping 23.2 V at 17.2 A). |
| 2 | A | passive | Anode, the terminal opposite the color band; connect to ground/return for the unidirectional KSMAJ14A (400 W peak pulse power on 10/1000μs). |
