Application Scenarios & Design Considerations

SWITCHMODE? Schottky Power Rectifier

Alternative Part Number

  • VS-30CTQ045-M3 --: 45V 30A dual common-cathode Schottky in TO-220 full-pack, same package style and higher current margin, direct functional replacement.
  • STPS30L45CFP --: 45V 30A dual Schottky rectifier in TO-220FP, comparable forward drop and thermal behavior, suitable drop-in substitute.
  • SBR30A45CTFP --: 45V 30A dual Schottky in TO-220FP with similar VF and reverse leakage, good alternative when ON parts are unavailable.
