Page 5: Introduction
It has a quasi-common drain design with a double gate structure using the Infineon gate injection transistor (GIT) technology. The CoolGaN™ BDS is fundamentally a five terminal device, two gates, two sources and substrate. It has four modes of operations: the traditional on/off modes and two diode modes where the switch can be actively controlled to behave like a diode that can block voltages in both directions.
