TO-263 (D2PAK)

Package: TO-263-2 Library: Package_TO_SOT_SMD Category: Power Package 3D Model: TO-263-2.step Format: STEP

Description

The TO-263 (D2PAK) is the surface-mount version of TO-220 for high-power applications. At 10 x 9mm with a massive thermal tab, it dissipates up to 2-3W without heatsinking and much more with PCB copper pour thermal relief. Houses high-current MOSFETs (IRF3205S), high-power voltage regulators, and power Schottky diodes. Roughly 50% larger than DPAK (TO-252), it handles higher thermal loads. The 3D model shows the large body, wide thermal tab, and two signal leads.
