Vishay Launches Automotive PV MOSFET Driver

Why It Matters

The VODA1275 cuts component count and cost in high‑voltage EV powertrains, accelerating the shift toward more compact, reliable vehicle electronics.

Key Takeaways

• 8 mm creepage distance in SMD‑4 package
• 1260 V peak isolation, 5300 VRMS test rating
• 80 µs turn‑on time, faster than peers
• Replaces two series drivers, cuts board space
• Optically isolated, no external supply needed

Pulse Analysis

The automotive sector is rapidly embracing higher voltage architectures to improve efficiency and range in electric and hybrid vehicles. Traditional MOSFET and IGBT drivers often require multiple components to meet isolation and voltage requirements, inflating board real‑estate and design complexity. Vishay’s new VODA1275 addresses this challenge by integrating a photovoltaic isolation scheme within a tiny SMD‑4 footprint, delivering an 8 mm creepage distance and a mold compound rated CTI‑600, which together meet stringent automotive safety standards while maintaining a compact form factor.

From a technical perspective, the VODA1275’s 1260 V peak isolation and 5300 VRMS test rating provide a robust safety margin for battery systems exceeding 800 V. Its 80 µs turn‑on time outpaces many legacy drivers, enabling faster pre‑charge and fault‑clearance sequences. The driver’s 20 V open‑circuit voltage allows designers to replace two series‑connected drivers with a single part, directly reducing component count, board space, and associated BOM costs. Additionally, the internal infrared emitter eliminates the need for an external supply, simplifying power budgeting and supporting solid‑state relay implementations that can supplant electromechanical relays in next‑generation vehicle architectures.

Market implications are significant as EV adoption accelerates and OEMs seek cost‑effective, reliable power electronics. The VODA1275’s AEC‑Q102 qualification assures compliance with automotive reliability standards, while its RoHS‑compliant, halogen‑free construction aligns with sustainability goals. With eight‑week lead times for sampling and volume production, Vishay positions the driver for immediate integration into upcoming vehicle platforms, potentially setting a new benchmark for high‑voltage driver consolidation in the automotive supply chain.
