DESCRIPTION

VS-HFA04TB60S 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 600 V and 4 A continuous current, the

VS-HFA04TB60S is especially well suited for use as the

companion diode for IGBTs and MOSFETs. In addition to

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

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-HFA04TB60S 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.
