SFF1040CT Dual Fast Recovery Rectifier Diode, 10A 400V (TO-220F, Common Cathode)

Product details

Description The SFF1040CT is a dual fast recovery rectifier diode , manufactured by AUK Corp, housed in the isolated 3-pin TO-220F through-hole package. The dual diode schematic printed on the package confirms a common-cathode configuration, integrating two independent fast recovery diodes on a single die — a common design for reducing part count and PCB space in dual-rectification circuits. This device is part of AUK's SF-series ultrafast recovery diode family, closely related to their SF10A40H (400V, 10A, single diode) datasheet line. Based on this family's characteristics, the SFF1040CT offers a 400V maximum repetitive reverse voltage with 10A average forward current per diode , along with fast reverse recovery time for reduced switching losses in high-frequency circuits. It features high voltage reliability, high-speed switching, low power loss, and high efficiency, and is halogen-free and RoHS compliant. Its isolated TO-220F package simplifies heatsink mounting since no separate insulating mica pad is typically required, while the dual common-cathode configuration makes it well suited for center-tapped rectification, dual-output power supplies, and other applications needing two matched fast recovery diodes in one compact package.
