Changjing · MOSFETs · SOT-523
CJE3134K from Changjing, in a SOT-523. 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 | GATE | input | Gate control terminal with ±12V maximum rating and 0.35-1.1V threshold voltage at ID=250µA. |
| 2 | SOURCE | passive | Source terminal serving as gate voltage reference and common drain current return path. |
| 3 | DRAIN | passive | Drain terminal rated 20V maximum voltage and 0.75A continuous drain current. |

- Symbol: `CJE3134K`
- Footprint: `Package_TO_SOT_SMD:SOT-523`
- 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `cje3134k-etched.step` / `cje3134k-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cje3134k.step` / `cje3134k.glb` are the bare package body.
