Driver-Circuit Design Considerations for High=Voltage Linen-Scan Transistor

Advances in technology have made available Silicon High Voltage Transistors for use in television line scan applications. The basic structure of such-devices is discussed comparing with conventional low voltage power devices showing the dominance of the high voltage devices collector region. It will be skhown how this large collector volume impacts on the common emitter characteristics, reducing gain, and the switching characteristics, due to the large amounts of collector stored charge.
