Test voltage must be applied within dv/dt rating. Note 3. This is static dv/dt. Commutating dv/dt is a function of the load–driving thyristor(s) only. Note 4. The NTE3048 is guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating IF lies between max IFT (15mA) and absolute max IF (60mA).
