DESCRIPTION

VS-HFA32PA120C... 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 16 A per leg continuous

current, the VS-HFA32PA120C... 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

(IRRM) and does not exhibit any tendency to “snap-off”

during the tb 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 VS-HFA32PA120C... 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.
