VSK.250, VSK.270, VSK.320 Series

Vishay Semiconductors

Standard Recovery Diodes, 250 A to 320 A (MAGN-A-PAK Power Modules)

MAGN-A-PAK

PRODUCT SUMMARY

IF(AV)	250 A to 320 A
Type	Modules - Diode, High Voltage

FEATURES

• High voltage

• Electrically isolated base plate

• 3000 VRMS isolating voltage

•Industrial standard package

•Simplified mechanical designs, rapid assembly

•High surge capability

•Large creepage distances

•UL approved file E78996

•Compliant to RoHS directive 2002/95/EC

•Designed and qualified for industrial level

DESCRIPTION

This new VSK series of MAGN-A-PAKs uses high voltage power diodes in two basic configurations. The semiconductors are electrically isolated from the metal base, allowing common heatsinks and compact assemblies to be built. They can be interconnected to form single phase or three phase bridges and the single diode module can be used in conjunction with the thyristor modules as a freewheel diode. These modules are intended for general purpose applications such as battery chargers, welders and plating equipment and where high voltage and high current are required (motor drives, etc.).
