Notes:
2. Test voltage must be applied within dv/dt rating.
3. All devices are 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 (2mA for FOD410 and FOD4108 and 1.3mA for FOD4116 and FOD4118 and the absolute
max I_F (60mA).
4. This is static dv/dt. See Figure 11 for test circuit. Commutating dv/dt is a function of the load-driving thyristor(s) only.
5. Isolation voltage, V_ISO, is an internal device dielectric breakdown rating. For this test, Pins 1, 2 and 3 are common,
and Pins 4, 5 and 6 are common.
Typical Application
Typical circuit for use when hot line switching is required.
In this circuit the “hot” side of the line is switched and the
load connected to the cold or neutral side. The load may
be connected to either the neutral or hot line.
R_in is calculated so that I_F is equal to the rated I_FT of the
part, 2mA for FOD410 and FOD4108, 1.3mA for
FOD4116 and FOD4118. The 39Ω resistor and 0.01µF
capacitor are for snubbing of the triac and may or may
not be necessary depending upon the particular triac
and load use.
