Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-89
2SC3357 RF from Slkor SLKORMICRO Elec, 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 (基极); the datasheet gives emitter-base breakdown VEBO 2.5 V max and emitter-base leakage IEBO 0.1 µA at VEB=1 V. |
| 2 | C | passive | Collector terminal (集电极); absolute limits are VCBO 20 V, VCEO 12 V and IC 100 mA, with collector-base leakage ICBO 0.1 µA at VCB=10 V. |
| 3 | E | passive | Emitter terminal (发射极); the datasheet gives no emitter-specific limit, only the device limits of Tj 150 °C and Tstg −65 to +150 °C. |
