The 175°C maximum junction gives thermal margin in under-hood environments. ## Package and mounting — D2PAK thermal pad Supplied in the TO-263-3 (D²Pak) surface-mount package with a tab that is the drain connection. The standard D2PAK footprint is shared with the STB80N4F6AG and STB85NF55T4.","metaTitle":"STB270N4F3 N-Channel MOSFET, 40 V 160 A, 2.5 mOhm, AEC-Q101","metaDescription":"STB270N4F3 N-channel 40 V 160 A MOSFET in D2PAK. 2.5 mOhm Rds(on) at 10 V.
