Achieve 600V 8A Performance With Hyper-Fast Rectifier

12 August 2015

Designed for PFC applications where achieving the lowest possible energy losses is criticalDesigned for PFC applications where achieving the lowest possible energy losses is criticalThe DSR8F600 600V 8A hyper-fast rectifier introduced by Diodes Inc. specifically aims to boost diode for power-factor correction (PFC) and continuous conduction mode (CCM) applications. The hyper-fast rectifier targets switched-mode power supplies (SMPS) that need to deliver a high output—greater than 75W—in end-equipment such as flat-panel TVs, servers and telecoms systems. In addition, the device meets regulatory standards in Europe, U.S., Japan and China that require improved energy efficiency.

A hyper-fast 20ns reverse-recovery time reduces PFC MOSFET switching losses, increases switching speed and improves energy efficiency, while a very fast soft recovery capability ensures ringing and EMI interference are reduced.

Boost diode recovery losses are minimized by a low 3.9A reverse-recovery current, which also reduces power dissipation in the MOSFET and lowers the risk of system failure. A low 1.95V forward voltage drop also minimizes boost diode conduction losses.

The DSR8F600, according to Diodes, provides best-in-class performance, generating the least noise and achieving the highest power efficiency. It is also the first of a family of hyper-fast rectifiers; future introductions will provide even higher voltages and currents.

Supplied in a TO220AC package, the DSR8F600 hyper-fast rectifier is available and priced from $0.39 each in 1k piece quantities.
