Key Specifications
| Complete manufacturer part number | STB40NF20 |
|---|---|
| Manufacturer | STMicroelectronics |
| Description | N-channel 200V - 0.038Ohm -40A- D2PAK/TO-220/TO-220FP/TO-247 |
| Package / case | D2PAK |
| Product category | Power MOSFETs |
| Pins | 3 |
| Package terminal convention (manufacturer cover drawing) | 3 numbered package terminals shown on the manufacturer cover drawing. The D2PAK reference has a shortened centre lead and heat-spreading tab; no fourth independent terminal is inferred. |
