D2PAK (TO-263) is the SMD version of TO-220 for high-power MOSFETs, voltage regulators, and IGBTs. The large tab solders to a PCB copper pour for thermal dissipation without a separate heatsink.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | Gate/Control | Control input | I/O |
| 2 | Drain/Output | Main current terminal | PWR |
| 3 | Source/Input | Return or input terminal | GND |
| TAB | Heatsink Tab | Large SMD tab Drain/Collector connected | PWR |
