Fairchild Semiconductor offers Stealth II and Hyperfast II diode technology as part of a total power device solution specifically designed to optimize LCD TV switch-mode power supply (SMPS) applications. The FFP08S60S and FFPF08S60S Stealth II diodes exhibit excellent soft recovery (tb/ta > 1.3) and very fast reverse-recovery time (trr < 25nS @ 600V breakdown voltage). These characteristics are ideal for reducing problematic EMI and MOSFET switching losses in CCM (continuous-current-mode) power factor correction (PFC) designs. Also introduced is the FFPF08H60S Hyperfast II diode. Featuring fast reverse-recovery time (trr < 35nS @ 600V breakdown voltage) and low forward-voltage drop (Vf < 2.1V), this diode helps reduce conduction losses to increase energy efficiency in DCM (discontinuous-current-mode) PFC designs. The Stealth II and Hyperfast II technology was developed to combine with, and complement, an array of Fairchild’s existing UniFET and SuperFET MOSFET technologies.
