When the first Model T Ford rolled off the Piquette Avenue plant assembly line in Detroit, transportation was revolutionized. Henry Ford had created an affordable automobile millions of people drove every day. Today, transportation is being revolutionized again with the creation and production of electric and hybrid vehicles that are affordable for millions. So, it's fitting that each year engineers, innovators, and thought leaders converge a few miles away from that assembly line for a conference and expo dedicated to the next innovation in transportation. Come be part of today's auto revolution.

Darrah offers Isolated SCR Modules featuring standard dual SCR modules witg integral water cooled bases. Our improved design has eliminated thermal barriers associated with separate cooling bases. This product line features industry standard dual SCR modules with integral water cooled bases. Our improved design has eliminated thermal barriers associated with separate cooling bases. This has increased current ratings by as much as 15%. In addition, because the Q20008 water connections are directly tapped to the module base, water leaks are virtually eliminated. To further enhance water integrity, each unit is 100% pressure tested at 150 PSI for one minute.

Rectifier diodes are split into two sub-classes: Normal recovery diodes and avalanche diodes. Rectifier diodes are generally used for conversion of AC (alternating current) to DC (direct current). Normal recovery diodes are optimized with respect to low conduction losses and are able to handle very large currents. Avalanche diodes are self-protected against transient over-voltages.
