For a board in production, the BOM line needs a pin-compatible swap or a redesign around a current-production part. The TO-220FP footprint is common, so a drop-in from another vendor is possible if the gate charge and Rds(on) align. ## Gate charge and switching — what the 33 nC buys you Total gate charge is 33 nC at 10 V. Input capacitance is 870 pF at 50 V drain-source. ## Where the 525 V rating lands it The 525 V Vdss suits offline applications. The 6 A continuous rating at 25 °C case derates with temperature.","metaTitle":"STF7N52DK3 N-Channel MOSFET, 525 V, 6 A, TO-220FP, Obsolete","metaDescription":"STF7N52DK3 SuperFREDmesh3 N-channel MOSFET, 525 Vdss, 6 A, 1.15 Ohm Rds(on), TO-220-3 Full Pack.
