# KTC3880Y

**Shikues** · Bipolar (BJT) · SOT-23

KTC3880Y from Shikues, in a SOT-23. 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 of the NPN transistor; the datasheet rates emitter-base voltage at 4 V maximum and DC current gain hFE at VCE=5V, IC=1mA at 40 to 200 (Y grade 100~200). |
| 2 | EMITTER | passive | Emitter of the NPN transistor; collector current is rated 200 mA continuous and emitter-base breakdown voltage is 4 V minimum. |
| 3 | COLLECTOR | passive | Collector of the NPN transistor; rated 30 V collector-base, 18 V collector-emitter, 200 mA continuous current, and 200 mW dissipation. |

## CAD (KiCad official)

- Symbol: `KTC3880Y`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ktc3880y-etched.step` / `ktc3880y-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ktc3880y.step` / `ktc3880y.glb` are the bare package body.
