Therefore, recommended operating IFlies between max IFT(15 mA for MOC3031M & MOC3041M, 10 mA for MOC3032M & MOC3042M, 5 mA for MOC3033M & MOC3043M) and absolute max IF(60 mA).

8 The mercury wetted relay provides a high speed repeatedpulse to the 100x scope probes are used, to allow high speeds The worst-case condition for static dv/dt is established by triggering the with a normal LED input current, then removing the current. The variable RTEST allows the dv/dt to be gradually increased until the continues to trigger in response to the applied voltage pulse, even after the LED current has been removed. The dv/dt is then decreased until the stops triggering. RC is measured at this point and 12.
