发明名称 FOUR LEAD MONOLITHIC DARLINGTON AND OPTO-ELECTRONIC IGNITION SYSTEM INCORPORATING IT
摘要 <p>A monolithic Darlington in which the transistors forming the Darlington pair are formed on a substrate together with a fourth terminal in addition to the normal three terminals provided for a Darlington pair, the fourth terminal being connected to the base electrode of the second transistor and the emitter electrode of the first transistor. The addition of the fourth terminal enables a control circuit for controlling the rate of switch off to be connected between the fourth terminal and the command collector electrode, this removing the effect which the stored charge on the base electrode of the first transistor has on the switching rate of the Darlington pair, thus enabling a faster switching rate to be achieved.</p>
