Product Catalog Discrete Semiconductors Fast Recovery Diodes Rectifier Diodes
Fast Recovery Diodes ROHM s RF series utilizes a unique process for the highest recovery characteristics in the industry. The novel design, which emphasizes low loss and high reliability, has been well received in the market, resulting in the number one share in the PDP (Plasma Display Panels) sector. Rectifier Diodes ROHM offers the high reliability RR series of rectifier diodes, featuring among the industry's highest class surge resistances for automotive use. The diodes are also ideally suited for strobe applications requiring high surge resistance due to their compact size.the SR series, by far the most popular rectifier diodes in the industrial, commercial, automotive sectors, is available in a standard version and a high speed rectification surface mount type. 0 Fast Recovery Diodes / Rectifier Diodes

Discrete Semiconductors Fast Recovery Diodes RF Series Summary These high voltage resistance diodes, ideal for use in switching power supplies of all types, feature among the fastest switching speeds in the industry along with low VF for improved efficiency and reduced loss. Features High-speed operation High performance Applications Switching power supplies PDPs (sustain circuits) PFC circuits Low VF and ultra-high switching speed Generally VF (forward voltage) increases with trr (reverse recovery time). However, optimization of device conditions has resulted in high trr with low VF.
