Designed specifically for use as a boost diode for PFC and continuous conduction mode applications, the DSR8F600 has been introduced by Diodes Incorporated. The 600V, 8A rectifier features a hyper-fast 20ns reverse-recovery time which reduces PFC MOSFET switching losses, increases switching speed and improves energy efficiency.

The target market is in SMPS that need to deliver an output greater than 75W in end-equipment such as flat-panel TVs, servers and telecomms systems, where new regulatory standards in Europe, the USA, Japan and China require improved energy efficiency.

A very fast soft recovery capability ensures ringing and EMI interference are reduced. Boost diode recovery losses are minimised 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 minimises boost diode conduction losses.

Aimed at designers of PFC circuits who need to achieve the lowest possible energy losses, the DSR8F600 provides best-in-class performance, generating the least noise and achieving the highest power efficiency. It is 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 priced from $0.39 each in 1,000 unit quantities.
