2 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

4 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.

Competitor Product Competitor Product VF (mv) 00 IR (A) 4 80ns ns ns 80ns Circuit Example PDP Sustain Power Recovery Circuit (Resonance Circuit) ROHM commands the largest market share in the field of fast recovery diodes for use in resonators for PDPs. Discharge current RFT4S can be recovered at Tj = 0 with high efficiency at 0A-00ns, and the high reliability design can easily resist steep current surges in the 0A range. A diverse lineup is offered, including A- to A-class FRDs for ring currents designed to be connected anti-parallel to IGBTs. 0 Fast Recovery Diodes / Rectifier Diodes
