Figure 12. Inverse-Parallel SCR Driver Circuit
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 330Ω.
Note: This optoisolator should not be used to drive a load directly. It is intended to be a discrete triac driver device
only.
