MALVERN, PA — Vishay Intertechnology Inc. (NYSE: VSH) introduced a new automotive-grade photovoltaic MOSFET driver designed for high-voltage vehicle applications.
The device, designated VODA1275, is the first of its kind in the SMD-4 package to provide an 8 mm creepage distance and a mold compound with a comparative tracking index of 600, according to the company.
Vishay said the driver is designed to improve safety and reliability in high-voltage automotive systems while reducing design complexity and cost.
The device delivers a typical open circuit voltage of 20 volts, short circuit current of 20 microamps, and a turn-on time of 80 microseconds, enabling faster switching performance in systems using MOSFETs and insulated-gate bipolar transistors.
The VODA1275 is rated for a working isolation voltage of 1260 volts peak and an isolation test voltage of 5300 volts RMS, making it suitable for battery systems exceeding 800 volts.
The company said the driver is AEC-Q102 qualified and intended for use in pre-charge circuits, wall chargers, and battery management systems in electric and hybrid vehicles.
The device’s higher output voltage allows designers to use a single driver instead of multiple components in series, which can reduce system size and cost, according to the company.
The optically isolated driver operates using an internal infrared emitter, eliminating the need for an external power supply.
Vishay said the product is compliant with RoHS standards and is halogen-free.
