Description
International Rectifier's HFA08TA60CS 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 4 amps per Leg continuous
current, the HFA08TA60CS 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
(I
) and does not exhibit any tendency to "snap-off" during the tb portion of
RRM
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
HFA08TA60CS 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.
