Description
International Rectifier's HFA25TB60 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 600 volts and 25 amps continuous current, the HFA25TB60 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
TO-220AC
extremely low values of peak recovery current (IRRM) and does not exhibit any
tendency to "snap-off" during thetb 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.
