Schottky Rectifier, 400 A

VSKCS409/150P

Vishay High Power Products

MECHANICAL DESCRIPTION

The Generation 5 of ADD-A-PAK module combine the

excellent thermal performance obtained by the usage of

direct bonded copper substrate with superior mechanical

ruggedness, thanks to the insertion of a solid copper

baseplate at the bottom side of the device.

The Cu baseplate allow an easier mounting on the majority

of heatsink with increased tolerance of surface roughness

and improved thermal spread.

The Generation 5 of ADD-A-PAK module is manufactured

without hard mold, eliminating in this way any possible direct

stress on the leads.

The electrical terminals are secured against axial pull-out:

they are fixed to the module housing via a click-stop feature

already tested and proved as reliable on other Vishay HPP

modules.

FEATURES

• Low forward voltage drop

• High frequency operation

• Guard ring for enhanced ruggedness and long term

reliability

• UL pending

• Totally lead (Pb)-free, RoHS compliant

• Designed and qualified for industrial level

DESCRIPTION

The VSKCS409.. Schottky rectifier common cathode has

been optimized for low reverse leakage at high temperature.

The proprietary barrier technology allows for reliable

operation up to 175 °C junction temperature.

Typical applications are in high current switching power

supplies, plating power supplies, UPS systems, converters,

freewheeling

diodes,

welding,

and

reverse

battery

protection.
