Ansas has announced the availability of SiC Schottky Barrier Diodes (SBDs) featuring lower loss and higher voltage capability compared to silicon-based SBDs and 4A,6A,8A,10A 650V SIC SBDs in TO-220AC package have been released recently. The internal insulation technology delivers a significant reduction in power losses, boosts operating frequencies, and increases the power density of the overall solution.
SiC SBDs feature a reverse recovery time (trr), which is much less than the 35nsec to 50nsec of conventional Si-based FRDs. As a result, recovery loss is much less than Si-based FRDs, decreasing heat generation as well. In addition, the products ensure more stable operation during temperature changes than silicon FRDs, contributing to ceramic isulators and heat sinks in devices.
Features ● High frequency operation ● High temperature operation to +175℃ ● Extremely low reverse recovery current ● Ceramic insulator and heatsink combined ● Positive temperature coefficient of forward voltage ● Reduces the switching power losses and increases the efficiency of the application. |  |
Applications
