**VIBRATION** · Bipolar Transistors - BJT · SOT-23

VT3356 from VIBRATION, 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 | passive | Base terminal of the VT3356 silicon microwave bipolar transistor; the datasheet's absolute maximum emitter-to-base reverse voltage VEBO is 3 V. |
