Description:
The SFF1606G is a high-current, glass-passivated super-fast rectifier diode, manufactured by Taiwan Semiconductor Corporation (TSC). Internally, the device is built as a diode array with a common-cathode configuration — two fast-recovery diode elements sharing a common cathode connection, useful for center-tap rectification in power supply designs.
Rated for 400V and capable of handling 16A, this rectifier is built for high-efficiency, low-loss power conversion. It offers a low forward voltage drop, fast switching (recovery times as low as ~35ns), high surge current capability, and high overall reliability — making it well suited for demanding industrial, automotive, and power supply applications. The part is UL Recognized, RoHS compliant, and halogen-free, with AEC-Q101 automotive-qualified variants also available.
The device comes in a TO-220F (isolated tab) package, allowing it to be mounted directly to a heatsink without a separate insulating pad — helpful for compact designs with multiple high-current rectifiers mounted close together.
