Suggested method of firing two, back-to-back SCR’s with a Fairchild triac driver. Diodes can be 1N4001; resistors, R1 and R2, are
optional 1 k ohm.
Suggested method of firing two, back-to-back SCR’s with a Fairchild triac driver. Diodes can be 1N4001; resistors, R1 and R2, are
optional 330 ohm.
Note: This optoisolator should not be used to drive a load directly. It is intended to be a trigger device only.
