Couplers deliver low LED trigger currents

Providing reinforced insulation and low LED trigger currents of 3mA max, the TLP267J and TLP268J are the latest Triac-output photocouplers from TEE. The reduced trigger current allows the devices to control output at a lower input current, thus contributing to lower power consumption.

The TLP267J device consists of a non-zero crossing photo triac, while the TLP268J consists of a zero crossing photo triac. Both devices are coupled to a long-life gallium-arsenide infrared emitting diode, with both also rated for an operating temperature range of -40°C to 100°C. The photocouplers feature a minimum rated isolation voltage of 3750Vrms, whilst also offering a creepage and clearance distances of 5mm, minimum. Both devices are compatible with 240V AC mains and meet the reinforced insulation class requirements of international safety standards.

Supporting a peak off-state voltage of 600V and an on-state current of up to 70mA, the devices 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. Easy-to-use, the devices support reflow mounting in accordance with latest JEDEC standards.
