Description
International Rectifier's HFA50PA60C is a state of the art center tap 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 600 volts and 25 amps per Leg continuous current, the
HFA50PA60C 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
TO-247AC
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 HFA50PA60C 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.
