DESCRIPTION
HFA08TB120S 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 1200 V and 8 A continuous current, the
HFA08TB120S is especially well suited for use as the
companion diode for IGBTs and MOSFETs. In addition to
ultrafast recovery time, the HEXFRED
extremely low values of peak recovery current (I
does not exhibit any tendency to “snap-off” during the t
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 HFA08TB120S 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.
