It targets hard-switched topologies in off-line power supplies, PFC stages, and lighting ballasts where the full-pack isolation simplifies heatsinking without a separate insulating pad. ## Temperature range and package — deployment scope The TO-220FP full-pack isolates the drain tab electrically from the heatsink, simplifying assembly in metal-enclosure designs.","metaTitle":"STFU18N65M2 MOSFET N-CH 650V 12A TO-220FP, 330mOhm, Active","metaDescription":"STMicroelectronics STFU18N65M2 N-channel 650V 12A MOSFET in TO-220FP full-pack. 330mOhm Rds(on), 20nC gate charge, -55°C to 150°C.
