Use these parts in triac drivers, programmable logic controllers, AC output modules and solid-state relays used in home appliances and white goods. TLP267J consists of a non-zero-crossing photo triac, while TLP268J consists of a zero-crossing photo triac. Both are coupled to a long-life gallium-arsenide infrared emitting diode (LED).

The photocouplers have a minimum rated isolation voltage of 3750 Vrms. They offer creepage and clearance distances of 5 mm minimum and meet the reinforced insulation class requirements of international safety standards. Both devices are compatible with an AC mains voltage of 240V. They support a peak off-state voltage of 600V minimum and an on-state current of up to 70 mA. They are rated for an operating temperature range of -40°C to 100°C.
