# TO-252 (DPAK)

The TO-252 (DPAK) is a surface-mount power package designed as the SMD equivalent of the TO-220. With a large drain/collector tab that solders directly to the PCB, it provides excellent thermal performance without a heatsink — up to 2W on a standard 1oz copper plane. Standard package for medium-power MOSFETs (IRFR3607, IRLR8743), voltage regulators (LM1117, AMS1117 in DPAK), and power transistors. The two leads plus tab design keeps routing simple while handling 5-10A depending on copper area.
