MBR30100CT Description

The MBR30100CT is a high-performance Schottky barrier diode in a TO-220AB package, featuring low forward voltage drop (VF) and ultra-fast switching, making it ideal for switch-mode power supplies, DC-DC converters, inverters, and high-frequency rectification. Its dual common-cathode design ensures high current handling with a 30A forward current and 100V reverse voltage, minimizing power loss and improving system efficiency.

Main Technical Parameters

The main technical parameters of MBR30100CT include:

  • Maximum reverse voltage (VRRM): 100V
  • Average forward rectified current (IF(AV)): 30A
  • Peak forward surge current (IFSM): 200A
  • Forward voltage drop (VF): Typical 0.82V
  • Maximum reverse leakage current (IR): 0.2mA
  • Operating junction temperature range (TJ): -65°C to +150°C

Electrical Characteristics Analysis

  • Low Forward Voltage Drop
    The typical forward voltage drop of the MBR10100CT is about 0.82V, which is lower than that of traditional silicon rectifiers (usually above 1.0V), which means less power loss when working at high current.
  • Fast Switching Characteristics
    One of the advantages of Schottky diodes is its extremely low reverse recovery time, which makes it very suitable for high-frequency power applications such as synchronous rectification, boost/buck converters, etc.
  • High Reverse Voltage
    Its 100V reverse voltage is capable of rectification tasks in higher voltage environments, improving the flexibility and stability of system design.

Typical Application Circuits

  • Switching power supply output rectification: used as output rectification diode in flyback or forward switching power supply, using its fast recovery characteristics to reduce switching loss.
  • DC-DC buck converter: used as freewheeling diode in synchronous buck converter
  • Polarity protection circuit: prevents reverse connection of power supply from damaging sensitive electronic equipment
  • Battery charging management: prevents reverse discharge of battery in charging circuit.
