Physical Electronics Devices and ICs

  1. The saturation currents of the two diodes are 1 and 2mA. The breakdown voltages of the diodes are the same and are equal to 100V. The current in the diode D1 if V=90 V is—


    1. 0 mA
    2. 1 mA
    3. 2 mA
    4. 3 mA
Correct Option: B

When, V = 90V, no diode reaches breakdown. Thus I is determined by smallest saturation current i.e. I = 1m A.
