HFA25TB60S

Vishay High Power Products

FEATURES

• Ultrafast recovery

• Ultrasoft recovery

• Specified at operating conditions

• Designed and qualified for industrial level

BENEFITS

• Reduced RFI and EMI

• Reduced power loss in diode and switching transistor

• Higher frequency operation

• Reduced snubbing

DESCRIPTION

HFA25TB60S 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 25 A continuous current, the

HFA25TB60S is especially well suited for use as the

companion diode for IGBTs and MOSFETs. In addition to

does not exhibit any tendency to “snap-off” during the

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 HFA25TB60S 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.
