Input capacitance measures 1145 pF at 25 V drain-source, which influences the switching speed and the gate-driver's peak current requirement. For designs targeting hard-switched topologies above 100 kHz, the gate charge and capacitance numbers should be factored into the driver selection and dead-time calculation. The TO-220 through-hole package suits designs where a heatsink is bolted to the tab for thermal management; the package's lead form is compatible with standard PCB layouts and chassis-mount approaches. For volume commitments or dual-source qualification, the base product number STP9NK65 covers the family, and the Z suffix denotes the SuperMESH™ generation.","metaTitle":"STP9NK65Z N-Channel MOSFET, 650 V, 6.4 A, TO-220","metaDescription":"STP9NK65Z N-Channel MOSFET from STMicroelectronics SuperMESH™ series. 650 V drain-source, 6.4 A continuous drain, 1.2 Ohm Rds(on) at 10 V.
