Phototriac Optocouplers feature blocking voltage of 600 Vac.

June 13, 2012

Housed in miniflat SOP-4 package with 2.0 mm height, VOM160 and VOM305x Series offer input trigger LED current of 5, 7, and 10 mA. Non-zero crossing phototriac optocouplers turn motors and solenoid controls on/off in refrigerators, lamps, washers, and coffee makers. Models VOM3052T and VOM3053T, with static dV/dt of 1,500 V/µs, are well suited for noisy environments where lower dV/dt can cause thyristor to be triggered as result of high slew rate transient on output load.
