# 2SC3357-RE

**Shikues** · Bipolar (BJT) · SOT-89

2SC3357-RE from Shikues, 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 | Base | input | Base terminal of the NPN RF transistor; the datasheet gives no base-specific limit, and the emitter-base breakdown voltage VEBO is rated at 3 V maximum. |
| 2 | Collector | passive | Collector terminal, rated for VCBO 20 V, VCEO 12 V and a collector current IC of 100 mA maximum. |
| 3 | Emitter | passive | Emitter terminal of the NPN transistor; the datasheet gives no emitter-specific limit beyond the absolute maximum ratings. |
