Vishay Launches First 8mm SMD-4 Automotive MOSFET Driver for EV Systems

Why It Matters

The VODA1275’s fast switching and robust isolation let OEMs shrink power‑train modules while supporting higher battery voltages, accelerating cost‑effective EV adoption.

Key Takeaways

• 8 mm creepage, 600 CTI mold compound.
• 1260 V peak isolation, 5300 VRMS test rating.
• Turn‑on time 80 µs, three times faster than rivals.
• Single driver replaces two, cuts board space and cost.
• AEC‑Q102 qualified for EV pre‑charge, chargers, BMS.

Pulse Analysis

The rapid rise of 800 V and higher battery architectures in electric vehicles has intensified demand for driver ICs that combine high voltage isolation with a minimal footprint. Vishay’s VODA1275 answers that call by delivering an 8 mm creepage distance and a mold compound rated at a comparative tracking index of 600, which far exceeds the typical automotive standard. This level of creepage and CTI enables reliable operation in the harsh thermal and humidity environments found under the hood, while the SMD‑4 package saves valuable PCB real‑estate in densely packed power modules.

Performance is another differentiator. The VODA1275 achieves an 80 µs turn‑on time—about three times faster than competing MOSFET drivers—allowing tighter control of pre‑charge circuits and reducing voltage overshoot during high‑current events. Its 1260 V peak isolation and 5300 VRMS test rating make it suitable for 800 V+ battery packs, and the 20 V open‑circuit output lets designers replace a series pair of drivers with a single device, cutting board area and component cost. The low‑current infrared emitter eliminates the need for an external supply, simplifying schematic design.

Beyond electrical specs, the VODA1275 meets AEC‑Q102 automotive qualification and adheres to RoHS, halogen‑free, and Vishay Green standards, aligning with OEM sustainability goals. With samples already available and an eight‑week lead time for production, the part is positioned for immediate integration into next‑generation EV platforms, including solid‑state relay replacements for legacy mechanical relays. As manufacturers push for higher efficiency and lower weight, the combination of compact size, fast switching, and robust isolation is likely to become a benchmark for future automotive MOSFET drivers.
