Title: Semiconductor device with type identifying terminal
Inventor: YABE KATSUHIKO
IPC: H01L21/822
Filed: 1985-08-28
Abstract: PURPOSE:To prevent management from mistaking by connecting a diode or a parallel circuit of one or more resistors between a plurality of type identifying terminals. CONSTITUTION:A diode D11 and a resistor R11 are connected in parallel between type identifying terminals P1 and P2, and a resistor R22 is connected between the type identifying terminals P2 and P3. A combination of the diode and the resistor connected between the terminals is altered according to the type. When a DC voltage of the polarity that the terminal P1 is positive and the terminal P2 is negative is applied, the terminals are conducted therebetween by the diode D11, but if the polarity is reversed, a current in response to the resistor R11 flows. A current in response to the resistor R22 flows without depending upon the polarity of the voltage between the terminals P2 and P3. Thus, the conduction or interruption between the terminals or the resistance value can be used as an index of the type of a semiconductor device.
