Vishay Optocoupler Series Boosts Efficiency, Targets Industrial Automation
Event summary
- Vishay Intertechnology released the VOx619A series of phototransistor optocouplers on February 25, 2026.
- The new series offers a 50% reduction in forward current compared to previous generations (0.5mA).
- VOx619A devices maintain >75% current transfer ratio (CTR) across a wide temperature range (-55°C to +125°C), improving signal fidelity.
- The optocouplers are available in four packages (DIL-4, LSOP-4, SOP-4, SSOP-4) with varying isolation voltages and creepage distances, with lead times of eight weeks.
The big picture
Vishay’s new optocoupler series addresses the growing demand for energy-efficient components in industrial applications, driven by stricter regulations and a focus on sustainability. The improved CTR and temperature range offer a competitive advantage in sectors like micro mobility, energy metering, and telecom, where signal integrity and reliability are paramount. This product launch reinforces Vishay’s position as a key supplier to the industrial electronics market, a segment experiencing steady growth alongside broader automation trends.
What we're watching
- Adoption Rate
- The success of the VOx619A series will depend on the speed at which industrial customers adopt the improved energy efficiency and signal fidelity, particularly in DC/DC converters and programmable controllers.
- Competitive Response
- Other semiconductor manufacturers will likely respond to Vishay’s offering with their own low-power, high-CTR optocoupler solutions, potentially leading to price pressure and increased competition.
- Temperature Resilience
- The extended operating temperature range (+125°C) positions Vishay favorably, but sustained performance under these conditions will be critical for maintaining reliability and customer satisfaction in demanding industrial environments.
