Test voltage must be applied within dv/dt rating.
All devices are guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating IF lies between max
IFT (15 mA for MOC3081, 10 mA for MOC3082, 5 mA for MOC3083) and absolute max IF (60 mA).
This is static dv/dt. See Figure 7 for test circuit. Commutating dv/dt is a function of the load–driving thyristor(s) only.
