# D882M

**Changjing** · Bipolar (BJT) · TO-252-2L

D882M from Changjing, in a TO-252-2L. 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 | BASE | input | Base terminal of the NPN transistor; the datasheet gives VEBO of 5 V and a base-emitter saturation voltage of 1.5 V at IC = 2 A, IB = 0.2 A. |
| 2 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet rates VCBO at 40 V, VCEO at 30 V, and continuous collector current IC at 3 A, with PC of 1.25 W. |
| 3 | EMITTER | passive | Emitter terminal of the NPN transistor; the datasheet gives VCE(sat) of 0.5 V at IC = 2 A, IB = 0.2 A and a maximum storage temperature of 150 ℃. |

## CAD (KiCad official)

- Symbol: `D882M`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252-2L (KiCad packages3D, STEP)
- 3D model files: `d882m-etched.step` / `d882m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `d882m.step` / `d882m.glb` are the bare package body.
