Application Scenarios & Design Considerations

SCHOTTKY ISOLATED PLASTIC RECTIFIER

Alternative Part Number

  • SBR10U45D1 --: 10A 45V Schottky barrier rectifier in TO-220 style package, higher current margin than the 7.5A MBRF745 and a different series/prefix, suitable for similar rectification and freewheeling roles.
  • STPS745D --: 7.5A 45V Schottky rectifier with comparable forward voltage and current rating, from a different manufacturer and naming series, making it a close functional drop-in for the MBRF745.
  • MBR745 --: 7A 45V Schottky barrier rectifier with nearly identical ratings and a distinct series name, offering a cost-effective alternative for the same application.
  • MBRF745-E3/45 --: Same 7.5A 45V Schottky barrier rectifier in ITO-220AC package with equivalent forward voltage and current ratings, widely available from a major manufacturer.
  • SBR745 --: 7.5A 45V Schottky rectifier with comparable VF and thermal characteristics, suitable drop-in replacement in most power supply and freewheeling applications.
