Qspeed Q Series Fast & Ultrafast Recovery Rectifier Diodes

Fast Silicon Diode with Superb EMI Behavior

Qspeed diodes have the lowest QRR of any Silicon diode. Their recovery characteristics increase efficiency, reduce EMI and eliminate snubbers. These features help designers improve the performance of their power conversion circuits.

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