Qspeed Q-Series Diodes

Description

Qspeed™ diodes have the lowest QRR of any Silicon diode. Their recovery characteristics increase efficiency, reduce EMI and eliminate snubbers.

Product Highlights

Features

  • Low QRR, Low IRRM, Low tRR
  • High dIF/dt capable (1000A/µs)
  • Soft recovery

Benefits

  • Increases efficiency
    • Eliminates need for snubber circuits
    • Reduces EMI filter component size & count
  • Enables extremely fast switching

Applications

  • Power Factor Correction (PFC) Boost Diode
  • Motor drive circuits
  • DC-AC Inverters
