DESCRIPTION

VS-HFA04TB60 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-HFA04TB60... 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-HFA04TB60... 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.
