MALVERN, PA — Vishay Intertechnology Inc. (NYSE: VSH) has introduced a new power module aimed at reducing space requirements and improving power efficiency in light electric vehicles and mild-hybrid automotive systems, a market where manufacturers continue to seek smaller and more efficient power electronics.
The new VS-HOT200C080 module is designed for 48-volt traction inverters used in light electric vehicles and belt-start generator systems found in mild-hybrid electric vehicles, according to the company.
The launch reflects ongoing competition among semiconductor suppliers to provide increasingly integrated power solutions as automakers and mobility manufacturers work to improve vehicle efficiency while reducing system size and complexity.
Vishay said the module can reduce circuit board space requirements by up to 15% compared with conventional discrete-component designs.
The company also indicated that the device’s integrated MOSFET technology delivers an on-resistance of 0.45 milliohms, which it claims can reduce conduction losses by 32% relative to competing products.
The module combines multiple components into a single package, including 80-volt MOSFETs configured in a half-bridge architecture, a shunt resistor for current measurement, bypass capacitors and a temperature-sensing NTC thermistor.
By integrating these functions into a single unit, manufacturers may be able to simplify system design and reduce the number of discrete components required in electric-drive applications.
The product is housed in a 30 mm by 22.8 mm FlatPAK HC0 package that incorporates an electrically isolated direct-bonded copper substrate.
Vishay stated that the module is designed to operate across temperatures ranging from minus 55 degrees Celsius to 175 degrees Celsius and is engineered to meet AQG-324 automotive reliability requirements.
The company also noted that the package separates signal and power connections, allowing designers to use dedicated printed circuit boards for each function. This configuration can simplify routing and enable stacked board designs where space constraints are critical.
The introduction comes as demand for power semiconductors continues to grow alongside global adoption of electrified transportation, particularly in lower-voltage vehicle architectures used in light electric mobility and mild-hybrid platforms.
