Non-zero crossing phototriac optocouplers save PCB space
The VOM160 and VOM305x series offer three choices of input trigger LED current: 5 mA (VOM160NT / VOM3053T), 7 mA (VOM160PT), and 10 mA (VOM160RT / VOM3052T). With a package height of only 2.0 mm, they feature a blocking voltage of 600 V AC for high-voltage applications.
In consumer applications, the VOM160 and VOM305x series will be used for turning on and off motors and solenoid control in refrigerators, washers, lamps and coffee makers. The new devices will also be used to drive TRIACs for solid-state relays and static AC power switches in industrial applications.
The VOM3052T and VOM3053T, with their high static dV/dt of 1500 V/µs, are particularly well suited for noisy environments where a lower dV/dt can cause a thyristor to be triggered as a result of a high slew rate transient on the output load, even without any triggering signal on the input.
Samples and production quantities of the new VOM160NT, VOM160PT, VOM160RT, VOM3052T and VOM3053T are available now.
