Description
International Rectifier's HFA06TB120 is a state of the art ultra fast 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 volts and
6 amps continuous current, the HFA06TB120 is especially well suited for use as the
companion diode for IGBTs and MOSFETs. In addition to ultra fast 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 HFA06TB120 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.
