Allegro MicroSystems Announces New SiC Schottky Barrier Diodes
Designed to Minimise Power Supply Loss in Large Data Processing Servers
Allegro MicroSystems has announced the release of a next generation series of SiC schottky barrier diodes, manufactured by Sanken Electric, Japan. The FMCA series achieves low leakage current and high speed switching at high temperatures. It is targeted at industrial and computer markets with end applications to include servers and those that require high frequency rectification circuits.
The FMCA series uses the next generation of power semiconductor SiC and a 650V breakdown voltage in a schottky barrier configuration, making it suitable for continuous current mode PFC circuits. These devices are capable of reducing the power loss that results from the recovery current. The diode's high-speed switching capability and energy-saving functionality allows for the potential downsizing of equipment, says Allegro.
Key features include improved efficiency of the power supply with low recovery loss characteristics of the SiC-SBD, low-resistance with a high-speed switching SiC-MOSFET that realises a compact and highly efficient power supply and an increased current within high temperature environments to maintain stable switching due to the elimination of thermal runway. The FMCA series is available in a TO-220F package.
