MBR4040CT Description

The MBR4040CT is a Schottky barrier rectifier diode widely used in power management systems. This device is widely used in switch mode power supplies (SMPS), DC-DC converters, inverters and various industrial equipment due to its low forward voltage drop, high current capability and fast switching characteristics.

Main Technical Parameters

The main technical parameters of MBR4040CT include:

  • Maximum reverse voltage (VRRM): 40V
  • Average forward current (IF(AV)): 40A (per device)/20A (per diode)
  • Peak forward surge current (IFSM): 250A
  • Forward voltage drop (VF): Typical 0.65V (at 20A)
  • Reverse leakage current (IR): Maximum 0.5mA (at rated VRRM and 125°C)
  • Operating junction temperature range: -55°C to +150°C
