At 25 °C junction, conduction loss at 1.75 A is about 11 W; at 100 °C junction the Rds(on) roughly doubles, so budget the thermal path accordingly. The 59 nC total gate charge at 10 V is moderate — a standard MOSFET driver can switch it at 50-100 kHz without excessive drive loss, but the input capacitance of 1154 pF at 25 V drain-source means the driver must source and sink enough peak current to charge and discharge the gate in the dead time.","metaTitle":"STF5NK100Z MOSFET, N-Ch 1000V 3.5A TO-220FP, Active","metaDescription":"STF5NK100Z N-channel MOSFET, 1000 V Vdss, 3.5 A continuous drain, 3.7 Ohm Rds(on), TO-220FP.

The STF5NK100Z is the SuperMESH3™ generation — the electrical ratings (1000 V Vdss, 3.5 A Id, 3.7 Ohm Rds(on)) are identical to the earlier STF5NK100, so it is a drop-in replacement in the same TO-220FP footprint.
