Vishay has unveiled its Gen VII series of general-purpose, high-voltage power modules that feature increased current handling, lighter weight, lower thermal resistance, improved reliability and lead-free construction.
Packaged in the TO-240AA-compatible Add-a-pak, the modules each integrate two active components in series and include standard diode, thyristor/diode, thyristor/thyristor and Schottky rectifier combinations.
The devices feature a high blocking voltage of up to 1600, a high dV/dt of 1000 V/µs, a high RMS voltage isolation capability of 3500 and a high surge capability of up to 3000 A.
The package construction eliminates the traditional copper base plate and instead features an exposed direct bonded copper substrate, which improves thermal performance by 20% and reduces weight to 75 g.
An aluminium/copper-clad wire bond interconnection improves reliability during power cycling and increases repeatability in manufacturing. The new construction also serves to eliminate certain process steps requiring the use of chemicals, and thus promotes cleaner and more environmentally friendly manufacturing.
Current ratings range from 26-105 A for the diode and thyristor combinations and from 110-400 A for the Schottky rectifier combinations.
Reverse voltage ranges from 400-1600 for the diodes and thyristors and from 30-150 for the Schottky rectifiers.
