2SB772L-P-TN3-R from UTC Unisonic Tech, in a TO-252. 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; the datasheet limits base current to IB = -0.6 A (absolute maximum DC). |
| 2 | C | passive | Collector terminal; the datasheet limits DC collector current to IC = -3 A (pulse -7 A) with VCBO = -40 V and VCEO = -30 V maximum. |
| 3 | E | passive | Emitter terminal; the datasheet limits emitter-base voltage to VEBO = -7 V maximum. |
