# 2SC3356

**Guangdong Hottech** · Bipolar (BJT) · SOT-23

2SC3356 from Guangdong Hottech, 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 | B | input | Base; the datasheet pin drawing shows B at the bottom-left lead (VEBO max 3 V, V(BR)EBO min 3 V). |
| 2 | E | passive | Emitter; the datasheet pin drawing shows E at the bottom-right lead (IC max 100 mA, PC max 200 mW). |
| 3 | C | passive | Collector; the datasheet pin drawing shows C as the single top lead (VCBO 20 V, VCEO 12 V, IC 100 mA max). |

## CAD (KiCad official)

- Symbol: `2SC3356`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `2sc3356-etched.step` / `2sc3356-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `2sc3356.step` / `2sc3356.glb` are the bare package body.
