    I'm using opto isolator 4n25 for my project.
    I've input of 5V from a pic pwm. I've to get the output at 20V to trigger an IGBT 15N120... can any one help me how to connect VCC and to draw the output? ..

    Hello umesh and welcome to All About Circuits.

    You have done well to post the pinout diagram for your opto-isolator.

    Do you understand its function and the operation of the diode and transistor within it?

    Since this is a school project we will not design your circuit for you but can help you design your own.
