TO-247 is a large through-hole power package for high-power MOSFETs, IGBTs, and power transistors capable of handling currents above 50A. Larger than TO-220 with bigger mounting hole for bolted heatsink attachment.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | Gate/Base | Control input | I/O |
| 2 | Drain/Collector | High current main terminal | PWR |
| 3 | Source/Emitter | Return current terminal | GND |
| TAB | Tab | Drain/Collector connected to tab for heatsink | PWR |
