STLD128DNT4 from STMicroelectronics, in a DPAK. 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 NPN transistor; base current is rated 2 A continuous and 4 A peak (tP < 5 ms). |
| 2 | C | passive | Collector, connected to the TAB; VCES is 700 V, VCEO is 400 V and collector current is 4 A (8 A peak). |
| 3 | E | passive | Emitter, with the integrated antiparallel collector-emitter diode connected between emitter and collector. |
