# 2SC5569G-AB3-R

**UTC Unisonic Tech** · Bipolar (BJT) · SOT-89

2SC5569G-AB3-R from UTC Unisonic Tech, 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 a base current absolute maximum of 1.2 A. |
| 2 | C | passive | Collector terminal of the NPN transistor; the datasheet rates collector current at 7 A continuous and 10 A pulsed, with VCBO 80 V and VCEO 50 V. |
| 3 | E | passive | Emitter terminal of the NPN transistor; the datasheet gives an emitter-base voltage absolute maximum of 6 V. |
