650 V, 5.4 A N-channel in a fully isolated TO-220
Typical applications include offline switch-mode power supplies, AC-DC converters, and power factor correction stages where 650 V blocking and moderate current handling are required.
On-resistance is specified at 1.3 Ohm maximum at 2.8 A drain current with 10 V gate drive — this is the conduction loss figure for the worst-case junction temperature.
It is ROHS3 compliant, and the base product number STF6 indicates a family of 650 V SuperMESH3 devices sharing the same TO-220FP footprint.
