The input capacitance is 380 pF at 100 V drain bias. ## Mounting and thermal interface The TO-220 package has a metal tab that is electrically connected to the drain. A thermal pad or mica insulator is needed between the tab and the heatsink unless the heatsink itself is at drain potential. The maximum power dissipation is 110 W at the case temperature — that is the theoretical limit with an ideal heatsink; real designs derate from there based on the thermal resistance of the interface and the ambient temperature.","metaTitle":"STP7N105K5 N-Channel MOSFET, 1050V 4A TO-220, SuperMESH5","metaDescription":"STP7N105K5 N-channel MOSFET from STMicroelectronics, 1050V Vdss, 4A Id, 2 Ohm Rds(on) at 10V.
