Frequently asked questions
What is the Rds(on) of STFU13N80K5?
The maximum Rds(on) is 450 mOhm, measured at 6 A drain current and 10 V gate drive. This is the worst-case value at 25°C junction temperature; actual on-resistance increases with temperature, so derate for the operating junction temperature in your application.
What is the maximum drain current of STFU13N80K5?
Continuous drain current is rated at 12 A at 25°C case temperature. The 800 V drain-source voltage rating and the 35 W maximum power dissipation define the safe operating area — the actual current capability is limited by junction temperature rise and heatsink thermal resistance in the end application.
Is STFU13N80K5 lead-free and RoHS compliant?
No separate lead-free statement is needed beyond the ROHS3 compliance marking.
