If you’re still using complex series chains of 1.2kV silicon diodes for high-voltage designs, you’re losing more than just board space—you’re losing efficiency.
The Quest Semi single die 10kV Silicon Carbide (SiC) Schottky Diode is a total gamechanger for power density. By replacing bulky legacy stacks, you drastically cut switching losses and shrink your system footprint.
The Challenge with Stacking
Stacking components is commonly used to increase power and performance, but it can lead to:
-
Increased design complexity
-
Thermal management challenges
-
Higher risk of failure
-
Larger system footprint
-
Increased production costs
A Smarter Solution
Quest Semiconductors have developed an innovative solution where a single component can deliver performance typically achieved through stacked devices — a capability that remains uncommon in the industry.
Through our partnership with Quest Semiconductors, Gamtech supports a new approach that eliminates the need for stacking, simplifying design and improving efficiency.
