Optocouplers by Würth Elektronik

PERFORMANCE. RELIABILITY. SERVICE.

Optocoupler by Würth Elektronik

With the new optocouplers, Würth Elektronik presents one of the latest additions to its optoelectronic product portfolio. The innovative design features a coplanar structure and high-grade silicon for total internal reflection. This ensures the isolation gap stay fixed during the production process and provide perfect isolation and protection for your application. The total internal reflection provide stable CTR over the whole temperature range and high CTR even at low current operation.

Provided in all industry standard packages. Available with all binnings ex stock. Samples free of charge.

Optocouplers - What’s that?

  • Transfers analog/ digital signals between two isolated circuits by using light transmission
  • Optoelectronic package with infrared LED & detector
  • The optical transmission takes place with an infrared light beam

Why Optocouplers?

  • Separation of low power control circuits from high power circuits (galvanic isolation)
  • Optocouplers protect your application against overvoltages
  • Safety Isolation: for circuits and persons from dangerous electrical installations
