TLP267J – Phototriac-Output Optocoupler – Toshiba

The Toshiba TLP267J is a single-channel phototriac-output optocoupler (optotriac) rated at 600 V off-state voltage with 3750 Vrms isolation in a compact 4-pin SO6 surface-mount package, ideal for AC load control and isolation.

The Toshiba TLP267J is a single-channel phototriac-output optocoupler (also called an optotriac or triac-output photocoupler) that pairs a GaAs infrared LED with a light-activated phototriac detector. It is designed to provide galvanic isolation between low-voltage control logic and AC mains-side loads, delivering 3750 Vrms isolation in a space-saving 4-pin SO6 surface-mount package. The non-zero-cross output makes it well suited to driving external power triacs and switching resistive or inductive AC loads in modern appliance and smart-home designs.
