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

Performance

High CTR in low current operation

Stable CTR over whole temperature range

Application Examples

Isolated Power Supplies

Providing robust galvanic isolation of feedback control loop in SMPS

Motor Driver / Control

Breaking ground loops and providing safety isolation in high-voltage motor drivers

AC or DC Voltage Detection

Safety isolation in phase-controlled AC motor, safety relays/switches, etc.

Industrial Control Systems

Ensuring noise immunity and safety in industrial environments
