The reduced trigger current enables the TLP267J and TLP268J devices, packaged in ultra-miniature S06 package, to control output at a lower input current which contributes to lower power consumption.

Both TLP267J and TLP268J have been designed for use 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.  The devices offer creepage and clearance distances of min. 5 mm and meet the reinforced insulation class requirements of international safety standards. Both devices are compatible with an AC mains voltage of 240 V. The devices support a peak off-state voltage of min. 600V and an on-state current of up to 70 mA.

The TLP267J and TLP268J are both rated for an operating temperature range of -40°C to 100°C. Additionally they are easy to use, because they support reflow mounting in accordance with latest JEDEC standards.
