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.
