The MDmesh™ II technology reduces on-resistance and gate charge compared to planar MOSFETs of the same voltage class. Gate charge totals 44 nC at 10 V gate-source, which keeps switching losses manageable in hard-switched topologies up to the 100 kHz range. Input capacitance measures 1280 pF at 50 V drain-source bias. This saves assembly time and improves thermal interface reliability. Maximum power dissipation is 30 W at case temperature. Junction temperature rating is 150 °C maximum. The 650 V drain-source voltage gives headroom for 400 V DC bus rails in power factor correction stages or flyback converters, with derating margin for switching transients. The 15 A continuous rating at 25 °C case temperature derates with case heating; at elevated case temperatures the usable current drops per the datasheet curve. At 270 mOhm maximum on-resistance, conduction loss at 7.5 A is roughly 15 W. For lower-duty or lower-current applications the 270 mOhm figure directly scales the I²R loss. Gate charge of 44 nC at 10 V means a 1 A gate driver charges the gate in about 44 ns, which is fast enough for 100 kHz hard-switching without excessive cross-conduction. Slower gate drive or higher switching frequency may increase switching losses.","metaTitle":"STF20NM65N N-Channel MOSFET, 650 V, 15 A, MDmesh II","metaDescription":"STF20NM65N N-channel MOSFET from STMicroelectronics MDmesh II series. 650 Vdss, 15 A continuous drain, 270 mOhm Rds(on).
