2SD2143TL from ROHM Semicon, in a TO-252-2(DPAK). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | NPN base; driven through built-in series resistor R1=3.5 kΩ and shunt resistor R2=300 Ω from base to emitter; BVCEO 60 V (50 V min, 70 V max). |
| 2 | C | passive | NPN collector (also exposed thermal tab); built-in zener diode to base and damper diode; VCEO 60±10 V, IC 2 A continuous (3 A pulse), PD 10 W at Tc=25°C, VCE(sat) 1.5 V max at IC=1 A. |
| 3 | E | passive | NPN emitter; VEBO 6 V max, IEBO 3 mA max at VEB=5 V. |
