600 V SuperMESH N-channel in an isolated full-pack
At 1 A the conduction loss is 4.8 W, which consumes nearly a quarter of the 20 W package dissipation limit. The specified drive voltage of 10 V means a standard 12 V gate-drive rail fully enhances the channel; a 5 V logic-level output will not saturate the device and will leave it operating in the linear region with higher losses. Total gate charge is 15 nC at 10 V, a light load for the gate driver.
The TO-220FP's full-plastic construction has a higher junction-to-case thermal resistance than a standard TO-220 with a metal tab, so the effective power handling is lower than the package outline suggests.
