Inverse−Parallel SCR Driver Circuit (MOC3041M, MOC3042M, MOC3043M) 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 330W. NOTE: This optoisolator should not be used to drive a load directly. It is intended to be a trigger device only. 300 260_C 280 260 >245°C = 42 Sec 240 220 200 180 Time above 160 183 °C °C = 90 Sec 140 120 100 1.822_C/Sec Ramp up rate 80 60 40 33 Sec 20 0 0 60 120 180 270 360 Time (s) Figure 13.
