A driver that swings to at least 4.5 V is needed. Input capacitance Ciss is 4880 pF at 15 V drain-source. ## Thermal reality: 135 W in the DPAK tab Maximum power dissipation is 135 W at case temperature — that figure assumes the tab is soldered to a large copper island with good thermal vias to an inner plane. In a real 1-oz two-layer board, the continuous current is derated well below 160 A; the package thermal resistance dominates. The DPAK (TO-252) footprint has a single exposed tab on the drain. The tab must be connected to the drain net with a copper area and thermal-via array for the 175°C junction rating. ROHS3 compliant, so the part passes current EU exemption rules for lead-free assembly.","metaTitle":"IRLR8743TRPBF N-Channel MOSFET, 30 V, 3.1 mOhm Rds(on), DPAK","metaDescription":"IRLR8743TRPBF from Infineon HEXFET® series: N-channel 30 V, 160 A, 3.1 mOhm Rds(on) at 10 V.
