# 2SC3356G-A-AE2-R

**UTC(Unisonic Tech)** · Bipolar Transistors - BJT · SOT-23

2SC3356G-A-AE2-R from UTC(Unisonic Tech), 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 | E | passive | Emitter terminal of the NPN transistor; the datasheet rates the emitter-to-base breakdown voltage BVEBO at 3 V. |
| 2 | B | passive | Base terminal of the NPN transistor; the device absolute maximum ratings give a collector-to-emitter voltage of 12 V and a collector current of 100 mA. |
| 3 | C | passive | Collector terminal of the NPN transistor; the device absolute maximum ratings give a collector-to-base voltage of 20 V and a collector current of 100 mA. |
