The MBRF20200CT is a dual Schottky barrier rectifier diode, rated for 20A total forward current and 200V reverse voltage, packaged in the isolated TO-220F (ITO-220AB) through-hole package with a common-cathode, center-tap configuration (2 x 10A per leg). Built using guard-ring die construction for enhanced transient protection, this SWITCHMODE-style Schottky rectifier is designed for demanding power supply and switching applications where efficiency and reliability matter.

As a Schottky diode, the MBRF20200CT offers a low forward voltage drop and fast switching characteristics compared to standard silicon rectifiers, resulting in reduced power loss and higher overall efficiency. It features high surge current capability, a lead-free, RoHS-compliant, halogen-free "Green" construction, and is well suited for use as a polarity protection diode, re-circulating (freewheeling) diode, or general switching diode in power circuits.

Its isolated TO-220F package simplifies mounting to a heatsink, since no separate insulating mica pad is typically required, making it convenient to integrate into power supply designs, motor drives, and other high-current rectification circuits.
