MBR10200FCT Description

The MBR10200FCT is a high performance Schottky barrier diode. It is a surface mount device in TO-220F package and is designed for high efficiency power conversion applications.

Main Technical Parameters

The main technical parameters of MBR10200FCT include:

  • Maximum reverse voltage (VRRM): 200V
  • Average forward rectified current (IF(AV)): 10A
  • Peak forward surge current (IFSM): 120A
  • Forward voltage drop (VF): Typical 0.95V (at 5A, 25°C)
  • Maximum reverse leakage current (IR): 0.05mA (at 100V, 25°C)
  • Operating junction temperature range (TJ): -55°C to +150°C

Electrical Characteristics Analysis

  • Low Forward Voltage Drop
    The typical forward voltage drop of the MBR1060FCT is about 0.75V (at 10A), 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.

Common Problems and Solutions

1.Overheating problem:

  • Efficiency is lower than expected:
  • Phenomenon: System efficiency is not ideal
  • Possible cause: Diode forward voltage drop causes loss
  • Solution: Consider using a lower VF model or synchronous rectification solution

2.Premature failure

  • Phenomenon: The diode works within rated parameters but still fails
  • Possible causes: Voltage transient exceeds rated value, mechanical stress, welding problem
  • Solution: Add transient voltage suppressor (TVS), check assembly process, ensure welding quality

3.Efficiency is lower than expected

  • Phenomenon: System efficiency is not ideal
  • Possible cause: Diode forward voltage drop causes loss
  • Solution: Consider using a lower VF model or synchronous rectification solution

Summary

MBR10200FCT is a rectifier diode product with stable performance, high efficiency and moderate cost. It is particularly suitable for power management scenarios that require high current and high efficiency. With the support of reasonable heat dissipation design, it can provide stable rectification performance and is one of the commonly used devices for power design engineers.
