DESCRIPTION

HFA25TB60 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 25 A continuous current, the
HFA25TB60 is especially well suited for use as the

25 A

companion diode for IGBTs and MOSFETs. In addition to
ultrafast recovery time, the HEXFRED
extremely low values of peak recovery current (I
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 HFA25TB60 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.
