The 60.5 nC total gate charge at 10 V means the gate driver needs to source about 60 nC per switching cycle; at 100 kHz that's 6 mA average drive current, well within a standard MOSFET driver's capability. ## Thermal and package — rework and mounting notes The TO-220FP full-pack body has no exposed metal tab — the plastic encapsulant is the thermal interface. Rated power dissipation is 30 W at case temperature, and the operating junction range is -55 to 150 °C. Through-hole mounting with the package screw hole lets you torque it to a heatsink with a standard M3 screw. The isolated package means no mica or sil-pad, which cuts assembly time and eliminates one failure point under thermal cycling.","metaTitle":"STP6NK90ZFP N-Channel MOSFET, 900 V, 5.8 A, TO-220FP","metaDescription":"STP6NK90ZFP N-Channel MOSFET from STMicroelectronics SuperMESH series. 900 V Vdss, 5.8 A continuous drain, 2 Ohm Rds(on) at 10 V.

A heatsink is required for any continuous operation above a few watts. The isolated full-pack package bolts directly to a heatsink without an insulator."},{"question":"What is the exact replacement for STP6NK90ZFP?","answer":"No official replacement or successor part is listed by STMicroelectronics for the STP6NK90ZFP. The base product number STP6NK90 includes the standard TO-220 variant (STP6NK90Z) and the full-pack variant (STP6NK90ZFP). If you need a pin-compatible alternative, the STP6NK90Z (non-isolated TO-220) shares the same die but requires an insulator for heatsink mounting."},{"question":"Is STP6NK90ZFP RoHS compliant?","answer":"Yes, the STP6NK90ZFP is ROHS3 compliant, meeting the EU Restriction of Hazardous Substances directive without exemptions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STP6NK90ZFP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STP6NK90ZFP when reusing this data.
