TOSHIBA · Bipolar (BJT) · TO-3P-3
2SA1941-O from TOSHIBA, in a TO-3P-3. 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 terminal; absolute maximum base current is -1 A and emitter-base voltage is -5 V. |
| 2 | C | passive | Collector terminal, connected to the heat sink tab; absolute maximum VCEO and VCBO are -140 V and collector current is -10 A. |
| 3 | E | passive | Emitter terminal, the common reference for the PNP power transistor. |
