DESCRIPTION

VS-HFA08TB120S is a state of the art ultrafast recovery

diode. Employing the latest in epitaxial construction and

advanced processing techniques it features a superb

combination of characteristics which result in performance

which is unsurpassed by any rectifier previously available.

With basic ratings of 1200 V and 8 A continuous current, the

VS-HFA08TB120S is especially well suited for use as the

companion diode for IGBTs and MOSFETs. In addition to

ultrafast recovery time, the HEXFRED® product line features

extremely low values of peak recovery current (IRRM) and

does not exhibit any tendency to “snap-off” during the tb

portion of recovery. The HEXFRED features combine to offer

designers a rectifier with lower noise and significantly lower

switching losses in both the diode and the switching

transistor. These HEXFRED advantages can help to

significantly reduce snubbing, component count and

heatsink sizes. The HEXFRED VS-HFA08TB120S is ideally

suited for applications in power supplies and power

conversion systems (such as inverters), motor drives, and

many other similar applications where high speed, high

efficiency is needed.
