MOC3031M, MOC3032M, MOC3033M, MOC3041M, MOC3042M, MOC3043M APPLICATION INFORMATION
Typical circuit (Figure 9, 10) for use when hot line the MOC3032M and MOC3042M, or 15 mA for the switching is required. In this circuit the “hot” side of the line MOC3031M and MOC3041M. The 39 ohm resistor and is switched and the load connected to the cold or neutral side. 0.01 mF capacitor are for snubbing of the triac and may or The load may be connected to either the neutral or hot line. may not be necessary depending upon the particular triac Rin is calculated so that IF is equal to the rated IFT of the and load used. part, 5 mA for the MOC3033M and MOC3043M, 10 mA for Rin 1 6 180 W Rin 1 6 360 W VCC HOT VCC HOT 2 MOC3031M 5 2 MOC3041M 5 MOC3032M MOC3042M 39 39 MOC3033M W* MOC3043M W* 3 4 115 VAC 3 4 240 VAC 0.01 0.01 1 kW 330 W LOAD NEUTRAL LOAD NEUTRAL *For highly inductive loads (power factor < 0.5), change this value to 360 ohms. *For highly inductive loads (power factor < 0.5), change this value to 360 ohms.
