FDA18N50 MOSFET is a high-voltage MOSFET that uses DMOS and planar stripe technology. The FDA18N50 MOSFET has been designed to lower on-state resistance, improve switching performance, and increase avalanche energy strength. FDA18N50 MOSFETs are excellent for power factor correction (PFC), flat panel display (FPD) TV power, ATX, and electronic light ballasts.
