Thyristor-Output Photocouplers

hyristor_thumbsnail_1

Thyristor-output photocouplers are used to control AC loads that are directly connected to a 100-Vac or 200-Vac commercial power supply or to protect power supplies, etc. against overvoltage conditions. An AC load of several amperes to several tens of amperes can be controlled with an LED current of 10+ mA by using a thyristor-output photocoupler in tandem with a power triac.

Features of Thyristor-Output Photocouplers

  • Half-wave control over a commercial power supply with up to 600 V peak repetitive off-state voltage
  • Small DC holding current of less than 1 mA ideal for shutdown circuit applications for a commercial power supply
  • Reduces the power consumption and package size of limiting resistors for a commercial power supply
