Vishay Launches High-Isolation Optocouplers for EVs and Solar Inverters
Event summary
- Vishay Intertechnology introduced two automotive-grade optocouplers (VOWA617A and VOWA618A) with a comparative tracking index (CTI) of 600, designed for electric vehicles (EVs) and solar inverters.
- The devices offer VIORM of 1500 Vpeak, VIOWM of 1060 VRMS, and external creepage and clearance distances of ≥ 11 mm, providing a ≥ 38% higher safety margin than typical 8 mm solutions.
- The optocouplers operate over a temperature range of -40°C to +125°C, with a junction temperature capability up to +145°C, and are RoHS-compliant and halogen-free.
- Samples and production quantities are available now, with lead times of eight weeks.
The big picture
Vishay's new optocouplers target the growing demand for high-voltage isolation in EVs and solar inverters, aligning with the push for safer and more efficient renewable energy and electric vehicle technologies. The introduction of these devices underscores the increasing importance of reinforced insulation in high-voltage applications, a trend driven by stricter regulatory standards and the need for enhanced safety in emerging technologies.
