Würth Elektronik optocouplers

Friday, 21 January, 2022 | Supplied by: Wurth Electronics Australia Pty


Würth Elektronik has expanded its optoelectronic portfolio with optocouplers in all common packages and CTR (current transfer ratio) values. This includes the WL-OCPT series of phototransistor optocouplers in DIP-4, SOP-4 and LSOP-4 packages and the WL-OCDA Darlington optocoupler series as DIP-4 and SOP-4.

The different packages are also available in a range of lead frame varieties. The CTR values of the components — classified according to binning type — range from 20 to 15,000%. In addition, the DIN EN 60747-5-5 certified components can be used in the operating temperature range from -55 to +110°C.

Galvanic isolation of low-power control circuits from high-power circuits is an important safety aspect in many applications. Optocouplers protect against interference and overvoltage in power supplies, chargers, computers, microprocessors, sequence controllers, programmable logic controllers, measuring devices and other applications.

In designing the optocouplers, Würth Elektronik has chosen the coplanar package with a constant isolation gap, for isolation up to 5000 V. High-quality silicone and polymer materials provide for 100% internal reflection and offer a stable CTR over the entire temperature range.

The optocouplers feature fast switching times and high DC transmission ratios even in low current operation. The copper lead frames are designed to provide optimal solderability and solid assembly in the application.
