DESCRIPTION
HFA08TB60S is a state of the art ultrafast 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 V and 8 A continuous current, the
HFA08TB60S is especially well suited for use as the
companion diode for IGBTs and MOSFETs. In addition to
ultrafast recovery time, the HEXFRED
®
product line features
extremely low values of peak recovery current (I
RRM
) and
does not exhibit any tendency to “snap-off” during the t
b
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 HFA08TB60S is ideally
suited for applications in power supplies (PFC boost diode)
and power conversion systems (such as inverters), motor
drives, and many other similar applications where high
speed, high efficiency is needed.
