Product details

Gate charge and switching — why 9.5 nC matters

Package and mounting — TO-251 IPAK

The TO-251 (IPAK) is a through-hole package with three short leads, designed for vertical mounting on a PCB. The metal tab on the back provides a low-thermal-resistance path to the board copper; for the 45 W maximum power dissipation rating, adequate copper area or a small heatsink is expected. The short-lead form factor suits designs where the device sits close to the board, reducing loop inductance in the drain-source path. Verify the hole pattern matches your layout — the IPAK footprint is similar to DPAK but with through-hole leads instead of surface-mount pads.
