Recommended drive voltage for minimum on-resistance is 10 V. Total gate charge is 100 nC at 10 V. ## Temperature range and thermal design The 450 W power dissipation at case temperature is a theoretical maximum with an ideal heatsink; real-world dissipation is limited by the thermal resistance of the TO-247 package and the heatsink interface. The long-lead variant adds clearance for high-voltage creepage on the PCB.","metaTitle":"STWA40N95DK5 N-Channel MOSFET, 950 V, 38 A, TO-247","metaDescription":"STMicroelectronics STWA40N95DK5 N-channel MOSFET, 950 V Vdss, 38 A Id, 130 mOhm Rds(on).
