Rectifiers Offer 50% Smaller Footprint and 90% Volume Reduction

SanRex DF product size evolution

PPM Power’s Three-Phase Diode Module range has been expanded with a new Dual Inline Package (DIP) from SanRex. They offer a 50% smaller footprint and 90% volume reduction compared directly to other 1600 V 100 A three-phase rectifiers. This offers a significant reduction in material costs, for cost-effective systems.

Reduced Manufacturing Costs

With this new product, SanRex brings PCB mount advantages to the 100 A class rectifier; reducing manufacturing costs by offering auto-insertion and wave soldering, rather than screw terminals.

Improved Thermal Management

The internal construction of the diode module has a copper heat spreader for reduced thermal resistance. With Vf reduced by more than 10%, the devices offer lower losses for a given current, reducing the heatsink size.

High Reliability

The module has been designed with no wire bonding and transfer molding technology to extend the product life. Testing shows three times greater thermal cycling capability than larger industry standard packages.
