10A and 20A Silicon Carbide Schottky Diodes

Allegro MicroSystems, LLC announces the release of the next generation series of silicon-carbide (SiC) Schottky barrier diodes (SBDs). The FMCA series achieves low leakage current and high speed switching at high temperatures and is offered by Allegro and manufactured and developed by Sanken Electric Co., Ltd. in Japan. This new series is targeted at the industrial and computer markets with end applications to include servers and those that require high frequency rectification circuits.

The FMCA offers 650 V 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.

Several key features of this new series are 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 realizes 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. Pricing for 1,000 pieces is $4.00 for the 10A FMCA-11065 and $6.50 for the 20A FMCA-22065.
