**Package:** TO-252-2
**Library:** Package_TO_SOT_SMD
**Category:** Power Package
**3D Model:** TO-252-2.step
**Format:** STEP

## Description

The TO-252 (DPAK) is the surface-mount evolution of the TO-220 power package. With a large drain tab for heatsinking and two signal leads, it handles up to 2W without external heatsinking. At 6.5 x 6.1mm, it houses power MOSFETs (IRFZ44NS), voltage regulators (78M05), and Schottky diodes. The 3D model shows the distinctive large thermal tab and formed leads.

## 3D Model Details
