Application NoteVishay Semiconductors7. What does “Inhibit Current I DINH ” means?I DINH is Off-state current in inhibit state of a zero-crossing phototriac, in short “Inhibit current”. Its testcondition is V D = V DRM , I F = I FT1 , T amb = 25 C.The inhibit current I DINH is a function of the LED forward current I F , shown as Figure 10 of its datasheet.(μA)V D = 600 VFig. 10 - Inhibit current vs. I F /I FT 25CFor example, V D = 600 V, T amb = 25 C, I FT1(max) = 2.0 mASupposeI F = 4 * I FT1 = 8 mAthenI DINH = 60 μA (typical)When a sensitive power triac is triggered by the ZC phototriac a gate resister R G may be required to avoiderror triggering by the inhibit current.mcai Page 6 11/10/2008
