High quality optoelectronic devices for safe circuit isolation

   Wurth Elektronik has expanded its portfolio of photoelectric products with all standard packages and optocouplers and CTR values. It is composed of WL-OCPT series phototransistor photocouplers in DIP-4, SOP-4 and LSOP-4 packages. The WL-OCDA Darlington optical coupler family offers DIP-4 and SOP-4.

    These different packages are also available in a variety of lead frame varieties. CTR values for parts - classified by packing type - range from 20% to 15000 %. In addition, DIN EN 60747-5-5 certified parts can be used for operating temperatures ranging from -55℃ to +110℃.

  Optical couplers protect against interference and overvoltage in power supplies, chargers, microprocessors, sequence controllers, computers, programmable logic controllers, measuring devices, and other applications. The company chose a coplanar package with a constant isolation gap when designing the optical coupler.

    This ensures perfect isolation up to 5000V. High quality silicone and polymer materials provide 100% internal reflection and provide stable CTR over the entire temperature range. Optical couplers provide fast switching time and high DC transmission ratio even in low current operation. Copper lead frames provide optimum weldability and reliable assembly in applications.
