2SAR553P5T100 from ROHM Semicon, 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 PNP transistor; VEBO max -6 V, IEBO max -1.0 µA at VEB = -4 V, IB = -35 mA used for VCE(sat) test. |
| 2 | C | passive | Collector (center lead, also the tab) of the PNP transistor; VCEO -50 V, VCBO -50 V, IC -2 A continuous, ICP -4 A pulsed. |
| 3 | E | passive | Emitter of the PNP transistor, connected to the most positive supply in typical high-side use. |
