MOSFETs Optimize SMPS

For designers of switch mode power supplies (SMPS), the latest UniFET II MOSFETs feature an improved body diode, reduced switching losses, and the capability of withstanding double the current stress during diode recovery dv/dt mode. The FDPF5N50NZ and the FDPF8N50NZ N-channel MOSFETS are based on Fairchild’s Planar technology, which allegedly offers a better figure of merit. The FDPF5N50NZ is a 500V, 4.5A, 1.5? device, featuring an RDS(ON) of 1.38?. The FDPF8N50NZ is a 500V, 8A, 0.85? device that features an RDS(ON) of 0.77?. Prices for the FDPF5N50NZ and FDPF8N50NZ are $0.69 and $0.86 each/1,000, respectively. FAIRCHILD SEMICONDUCTOR, San Jose, CA. (800) 341-0392.
