Description
International Rectifier's HFA08TB60PbF 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 per-
formance which is unsurpassed by any rectifier previously available. With basic ratings of 600 volts and 8 amps per Leg
continuous current, the HFA08TB60PbF is especially well suited for use as the companion diode for IGBTs and
MOSFETs. In addition to ultra fast recovery time, the ultra fast recovery diode 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
ultra fast recovery diode features combine to offer designers a rectifier with lower noise and significantly lower switching
losses in both the diode and the switching transistor. These ultra fast recovery diode advantages can help to significantly
reduce snubbing, component count and heat sink sizes. The HFA08TB60PbF 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.
