Abstract
PURPOSE: To arrange each Zener diode so that each depletion layer respectively generating in a transistor collecter area arround the Zener diodes on both side when the highest voltage is applied on the transistor collecter.
CONSTITUTION: The intervals between each Zener diode ZD1, ZD2, ZD3, ZD4 will be made not equal and narrowed up to such a width as each depletion layer will not contact each other, when the highest voltage is applied on a collecter according to the extent of the depletion layer generating arround the Zener diodes on both sides. By doing so, no useless part will arise between each Zener diode.
