2SC3357U from CBI, 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 | input | Base of the NPN transistor; VEBO max 3.0 V, and collector current is rated up to 100 mA. |
| 2 | C | passive | Collector (also the tab) of the NPN transistor; VCBO max 20 V, VCEO max 12 V, IC max 100 mA. |
| 3 | E | passive | Emitter of the NPN transistor; VEBO max 3.0 V relative to the base. |
