Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
2. Test voltage must be applied within dv/dt rating.
3. This is static dv/dt.. Commutating dv/dt is a function of the load−driving thyristor(s) only.
4. 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
(2 mA for FOD420 and FOD4208 and 1.3 mA for FOD4216 and FOD4218) and the absolute max IF (30 mA).
5. Isolation voltage, VISO, 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. 5,000 VACRMS for 1 minute duration is equivalent to 6,000 VACRMS for 1 second duration.
