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.
* TLP748J with clearance and creepage distances of 8 mm are available.
To order photocouplers in a package with guaranteed clearance and creepage distances of 8 mm, suffix the part number with the letter F.
