Sanken Electric launches' world's fastest 'rectifier diode to help reduce PDP power consumption

c with a reverse recovery time (the time it takes to release accumulated charges when the applied voltage changes from forward to reverse) of 18 ns, which is more than 40% shorter than the company's original product. Samples were supplied starting from September 15th, 2005. The short reverse recovery time has reached the "highest level in the world" (Sanken Electric). Mainly targeting the field of PDP TV driver circuits.

In the field of PDP television, the industry is currently intensifying the development of high-efficiency solutions aimed at reducing power consumption, as well as low-noise solutions aimed at improving image quality. Therefore, for rectifier diodes used in driving circuits, there is an increasing demand to shorten the reverse recovery time and reduce the noise of the rectifier diode itself in order to reduce power loss.

Based on the relationship between reduced reverse recovery time and increased noise, Sanken Electric has improved the structure of rectifier diodes. A structure called "junction barrier Schottky" is adopted, and a "Schottky diode" structure that can effectively reduce noise is added to the "pn junction" structure, and the two structures are arranged side by side. This achieves low noise. Meanwhile, by optimizing the "survival time control technology" that can shorten the disappearance time of a few potential barriers when applying reverse voltage, the reverse recovery time has been improved.diode

The FMXJ series has three models: FMXJ-1103S, FMXJ-1104S, and FMXJ-2164S. The withstand voltage and average forward current of the three are 300V and 10A, 400V and 10A, and 400V and 16A, respectively. All are packaged in TO-220F. The sample prices are 240 yen, 260 yen, and 300 yen, respectivelydiode
