FDMC7660DC N-Channel Dual CoolTM PowerTrench® MOSFET is a 30V, 40A, 2.2mΩ MOSFET. It is manufactured using Fairchild Semiconductor’s advanced PowerTrench® process. This device integrates the advantages of both silicon and Dual CoolTM package technologies, offering the lowest rDS(on) while maintaining excellent switching performance by extremely low Junction-to-Ambient thermal resistance. It is ideal for use in DC/DC converters as a synchronous rectifier, telecom secondary side rectification and high end server/workstation.
