Note 2. Test voltage must be applied within dv/dt rating.
Note 3. This is static dv/dt. Commutating dv/dt is a function of the loaddriving thyristor(s) only.
Note 4. The NTE3048 is guaranteed to trigger at an I
F
value less than or equal to max I
FT
. Therefore,
recommended operating I
F
lies between max I
FT
(15mA) and absolute max I

(60mA).
