SMDJ24AQ from Yangzhou Yangjie Elec Tech, in a DO-214AB(SMC). 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 band on uni-directional types (SMDJ24AQ: VRWM 24 V, VBR 26.7-29.5 V at 1 mA, max clamping voltage 38.9 V at 77.12 A). |
| 2 | A | passive | Anode terminal of the uni-directional TVS diode, opposite the cathode band; 3000 W peak pulse power with a 10/1000 µs waveform. |
