It comes in a through-hole I-PAK (TO-251) package with short leads, which means it sits low on the board and takes a hot-air station or soldering iron without lifting pads — useful for bench rework or field repair. ## Gate charge and switching — what 11 nC means for the driver Gate charge is 11 nC at 10 V. Input capacitance is 334 pF at 100 V Vds. ## Package and mounting — I-PAK for single-hole through-hole The I-PAK (TO-251) is a three-lead through-hole package with the tab as the drain. It mounts into a single hole on the PCB, which is quicker to hand-solder than a D²PAK reflow and easier to probe during bring-up. The short leads mean the part sits flush against the board — no bent-lead clearance issues.","metaTitle":"STU4N52K3 N-Channel MOSFET, 525V 2.5A I-PAK - SuperMESH3","metaDescription":"STU4N52K3 N-channel 525V 2.5A MOSFET in I-PAK. 2.6 Ohm Rds(on), 11 nC gate charge.
