Abstract

PURPOSE:To form the equivalent PNPN switch on the semiconductor substrate with use of two units of the transistor and then securing the ON/OFF control for the switch. CONSTITUTION:Equivalent PNPN switch 3 consists of transistor TR4 containing two collectos and TR5 featuring the opposite polarity to TR4, and is then connected with ON/OFF control TR6 and 7 as shown in the figure. With the current driving given through terminal C1, gate GP is driven and switch 3 is turned on by the self positive feedback function with this turn-ON state kept. At the same time, TR7 connected to additional collector c is also turned on. With driving of terminal C2, TR6 is turned on and a short circuit is given between the gate and the cathode of switch 3. Thus switch 3 has no positive feedback function and is thus turned off with TR7 turned off as well.
