2SB1198-RQ from Yangzhou Yangjie Elec Tech, 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 | input | Base of the PNP transistor; VEBO limit is -5 V and base current is -50 mA in the VCE(sat) test at IC=-500 mA. |
| 2 | E | passive | Emitter of the PNP transistor; emitter-base breakdown voltage is -5 V min at IE=-50 uA. |
| 3 | C | passive | Collector of the PNP transistor; VCEO is -80 V and continuous collector current is -500 mA max. |
