That is the conduction loss floor at 25 °C junction; multiply by the temperature coefficient from the datasheet's normalised curve to budget for the 150 °C hot case. Gate charge totals 5.7 nC at 10 V, which means a simple 10 V gate-drive rail with a 10 Ohm series resistor can switch this FET at 100 kHz without exceeding the driver's peak current capability. ## Military temperature range — rated for harsh environments The 2 W power dissipation at 25 °C ambient assumes a minimum copper area on the SOT-223 drain tab; derate above that temperature per the package's thermal resistance.","metaTitle":"STN1NF20 N-Channel MOSFET, 200 V, 1 A, SOT-223","metaDescription":"STN1NF20 N-Channel MOSFET, 200 V Vdss, 1 A continuous drain, 1.5 Ohm Rds(on) at 10 V, SOT-223 package.
