PRODUCT SUMMARY
IF(AV)
300 A
MECHANICAL DESCRIPTION
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 VSKCS301.. 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.
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.

Formula used: TC = TJ - (Pd + PdREV) x RthJC
;
Pd = Forward power loss = IF(AV) x VFM at (IF(AV)/D) (see fig. 6);
PdREV = Inverse power loss = VR1 x IR (1 - D); IR at VR1 = 80 % rated VR
