ROHM Semiconductor Super Fast Recovery Diodes

ROHM Semiconductor Super Fast Recovery Diodes are designed to improve the efficiency of switching power supplies. These diodes feature silicon epitaxial planar, low forward voltage, and low switching loss. These RFNxLBxS are ideal for general rectification applications.

Features

  • Repetitive peak reverse voltage:
    • 400V (RFN2LB4S and RFN3LB4S)
    • 600V (RFN2LB6S and RFN3LB6S)
  • Average rectified forward current:
    • 2A (RFN2LB4S and RFN2LB6S)
    • 3A (RFN3LB4S and RFN3LB6S)
  • Peak forward surge current:
    • 35A (RFN2LB6S and RFN3LB6S)
    • 55A (RFN2LB4S and RFN3LB4S)
  • Small power mold type
  • Low forward voltage
  • Low switching loss
  • Ideal for general rectification
