APPLICATION INFORMATION

Basic Applications

Typical circuit for use when hot line switching is required.

In this circuit the “hot” side of the line is switched and the

load connected to the cold or neutral side. The load may be

connected to either the neutral or hot line.

Rin is calculated so that IF is equal to the rated IFT of the

part, 15 mA for the MOC3061M, 10 mA for the

MOC3062M, or 5 mA for the MOC3063M.

The 39

W resistor and 0.01 mF capacitor are for snubbing

of the triac and is often, but not always, necessary depending

upon the particular triac and load used.

Suggested method of firing two, back−to−back SCR’s

with a onsemi triac driver. Diodes can be 1N4001; resistors,

R1 and R2, are optional 330

W.

NOTE:

This optoisolator should not be used to drive a load

directly. It is intended to be a trigger device only.
