40 KHz+ operating ultrafast diodes with fast recovery time and low Vf

Vishay Intertechnology has released 11 new Gen2 650 V FRED Pt Ultrafast diodes. Vishay says the “H” family of bare die devices, suitable for applications working above 40 KHz, combine extremely fast and soft recovery time with low forward voltage drop and reverse leakage current to reduce switching losses in solar inverters, UPS, electric vehicles and hybrid electric vehicles, welding machines, servers, and continuous conduction mode power factor correction (CCM PFC). The “U” series, available on request for applications up to 40 KHz, offers a much lower forward voltage drop to optimize conduction losses.

FRED Pt Ultrafast diodes available in rated currents from 2 A to 150 A with high blocking voltage feature. The equivalent packaged devices are available on request.

FRED Pt Ultrafast diodes feature typical reverse recovery times down to 28 ns at +25 °C (di/dt = 200 A/µs), and forward voltage down to 1.38 V typical. The diodes offer a maximum operating junction temperature of +175 °C.

Sample and production quantities of the new FRED Pt Ultrafast diodes are available now, with lead times of 12 weeks for larger orders.
