Optocoupler, Phototriac Output, Zero Crossing, High dv/dt, Low Input Current 2842- i79030_4 A C 2 NC 3 ZCC* 4 MT *Zero crossing circuit 6 5 V D E MT2 NC FEATURES High static dv/dt 5 kv/μs High input sensitivity I FT =.6 ma, 2 ma, and 3 ma 300 ma on-state current Zero voltage crossing detector 700 V and 800 V blocking voltage DESCRIPTION The VO457 and VO458 consists of a GaAs IRLED optically coupled to a photosensitive zero crossing TRIAC packaged in a DIP-6 package. High input sensitivity is achieved by using an emitter follower phototransistor and a cascaded SCR predriver resulting in an LED trigger current of.6 ma for bin D, 2 ma for bin H, and 3 ma for bin M. The new phototriac zero crossing family uses a proprietary dv/dt clamp resulting in a static dv/dt of greater than 5 kv/μs. The VO457 and VO458 isolates low-voltage logic from 20 V AC, 240 V AC, and 380 V AC lines to control resistive, inductive, or capacitive loads including motors, solenoids, high current thyristors or TRIAC and relays.

If the spike potential exceeds the inhibit voltage of the zero-cross detection circuit, half of the TRIAC will be held-off and not turn-on. This hold-off condition can be eliminated by using a capacitor or RC snubber placed directly across the power triac as shown in fig.. Note that the value of the capacitor increases as a function of the load current. The hold-off condition also can be eliminated by providing a higher level of LED drive current. The higher LED drive provides a larger photocurrent which causes the phototransistor to turn-on before the commutating spike has activated the zero-cross detection circuit. For example, if a device requires.5 ma for a resistive load, then 2.7 ma (.8 times) may be required to control an inductive load whose power factor is less than 0.3.
