Littelfuse Schottky ultra-fast rectifiers DUR series provide ultra-fast switching speed. This series is designed to meet the general requirements of commercial and industrial applications.

The Schottky ultra-fast rectifiers DUR series are popular with designers because of their ultra-fast switching speed with very low reverse recovery time (T_rr), high blocking voltage (up to 1200 V), low leakage, and low forward voltage drop. This makes it possible to minimize power loss and increase efficiency during converter operation. Their higher junction temperature capability and low leakage provide higher reliability in harsh, high temperature environments.

The Schottky ultra-fast rectifiers DUR series can be used in applications, requiring uninterruptible power supplies, high frequency switch-mode power supplies, and DC-DC converters, and can also be used as anti-parallel diodes for high frequency switching devices such as IGBTs. Other applications include inductive heating/melting and ultrasonic cleaners and welders.

DUR series power semiconductors offer these key benefits:

• The DUR series’ ultra-fast switching speed and very low reverse recovery time make it suitable for high frequency applications with minimal switching loss
• The DUR series’ high blocking voltage (up to 1200 V) and low leakage makes it suitable for high voltage applications
• The series offers very low forward voltage drop and less heat dissipation than conventional diodes, thereby reducing thermal and electrical conduction losses
• Its high junction temperature capability improves reliability in high ambient temperatures or applications with minimal cooling available
