2SD2211T100R 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 | Base | input | Base terminal of the 2SD2211 transistor; the datasheet gives emitter-base breakdown BVEBO of 5 V minimum at IE = 50 µA and an absolute maximum VEBO of 5 V. |
| 2 | Collector | passive | Collector terminal; absolute maximum ratings are VCBO 160 V, VCEO 160 V, and DC collector current IC 1.5 A (pulse rating given in footnote 1). |
| 3 | Emitter | passive | Emitter terminal, referenced by the VEBO absolute maximum of 5 V and the VBE(sat) and VCE(sat) test conditions (IC/IB = 1 A/0.1 A). |
