# D882H

**hongjiacheng** · Bipolar (BJT) · SOT-89

D882H from hongjiacheng, in a SOT-89. 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 | B | passive | Base terminal of the NPN transistor; the datasheet gives emitter-base breakdown V(BR)EBO of 6.0 V minimum at IE=100 μA and emitter-base cut-off current IEBO of 1.0 μA maximum at VEB=6.0 V. |
| 2 | C | passive | Collector terminal; limits are collector-base voltage VCBO of 70 V, collector current IC of 3.0 A and collector power dissipation PC of 500 mW. |
| 3 | E | passive | Emitter terminal; the datasheet gives an emitter-base voltage VEBO rating of 6.0 V. |

## CAD (KiCad official)

- Symbol: `D882H`
- Footprint: `Package_TO_SOT_SMD:SOT-89-3`
- 3D model: SOT-89 (KiCad packages3D, STEP)
- 3D model files: `d882h-etched.step` / `d882h-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `d882h.step` / `d882h.glb` are the bare package body.
