Littelfuse's two new power semiconductor products outperform traditional switching diodes

Leth Corporation, a global leader in circuit protection, has added two more series to its growing power semiconductor products: MBR Series Schottky Barrier Rectifiers (Standard Schottky) are the latest devices based on silicon Schottky diode technology. The DUR series of ultra-fast rectifiers deliver ultra-fast switching speeds.

Both series are designed to meet the general requirements of commercial and industrial applications, and will be on display at the leading exhibition of the Chinese electronic components industry, March 15-17, 2016, at the Shanghai Electronics Show in Munich. Column. (E3 Hall, Booth #3522)

Schottky barrier rectifiers are very popular among designers because of their extremely fast switching speed, very low forward voltage drop, low leakage and high junction temperature capability; similarly, the DUR series of ultrafast rectifiers are also Its ultra-fast switching speed, very low reverse recovery time (TRR), high blocking power supply (up to 1200V) and low forward voltage drop make it possible to reduce power consumption and increase efficiency during converter operation. Its high junction temperature capability and low leakage provide higher reliability in harsh high temperature environments.

Typical applications for the MBR series of Schottky barrier rectifiers include uninterruptible power supplies, high frequency switching power supplies and DC-DC converters, as well as freewheeling diodes and polarity protection diodes. The DUR series of ultrafast rectifiers are suitable for all of these applications, plus anti-parallel diodes for high frequency switching devices such as IGBTs, induction heating and melting, and ultrasonic cleaners and welders.

"The MBR series and the DUR series represent the important new members of Lite's growing power semiconductor products," said Corey Deyalsingh, Director of Power Control Semiconductors. "I believe they will help increase the depth of our power semiconductor portfolio." To expand our range of applications."

The key advantages of the MBR series and DUR series power semiconductors are as follows:

• The extremely fast switching speed of the MBR Series and the ultra-fast switching speed of the DUR Series and very low reverse recovery time make them ideal for high frequency applications and minimize switching losses.

The high blocking voltage (up to 1200V) and low leakage of the DUR series make it suitable for high voltage applications.

Both series have very low forward voltage drop and lower heat dissipation than conventional diodes, thus reducing thermal and electrical conduction losses.

• Their high junction temperature capability increases reliability in applications with high ambient temperatures or where sufficient cooling is not available.
