MSKSEMI · Bipolar Transistors - BJT · SOT-223
BCP56-MS from MSKSEMI, in a SOT-223. 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 transistor; the emitter-base breakdown voltage V(BR)EBO is specified with a minimum of 5 V at IE=10μA. |
| 2 | COLLECTOR | passive | Collector terminal; continuous collector current IC is rated at 1 A and collector-emitter voltage VCEO is 45 V, 60 V or 80 V depending on type. |
| 3 | EMITTER | passive | Emitter terminal; the base-emitter breakdown voltage V(BR)EBO is specified with a minimum of 5 V. |
