TO-252 (DPAK)

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.
