Optocoupler, Phototriac Output, Zero Crossing, High dV/dt, Low Input Current


  • High isolation distance on output
  • High static dV/dt 1000 V/μs
  • High input sensitivity IFT = 5 mA
  • 100 mA on-state current

The VOT8026A consists of a GaAs IRLED optically coupled to a photosensitive zero crossing TRIAC packaged in a DIP-6 package.

VOT8026A isolates low-voltage logic from 120 VAC, 240 VAC, and 380 VAC lines to control resistive, inductive, or capacitive loads including motors, solenoids, high current thyristors or TRIAC and relays.
