en.Wedoany.com Reported - Vishay Intertechnology has introduced the VS-HOT200C080 integrated power module, rated at 200 amperes, targeting 48-volt traction inverter applications in light electric vehicles and mild hybrid electric vehicles. The device is designed to reduce system size while enhancing power conversion efficiency and reliability in automotive powertrains.
This module integrates 80-volt MOSFETs in a half-bridge configuration, optimized for belt-driven starter generator systems, energy recovery functions, and compact electric traction platforms. Compared to traditional discrete-component-based solutions, this solution can reduce printed circuit board space requirements by up to 15%.
A key feature of the VS-HOT200C080 is its low MOSFET on-resistance of 0.45 milliohms, which the company claims is among the best in its class. Compared to competing solutions, the lower RDS(on) helps reduce conduction losses by up to 32%, thereby improving system efficiency and reducing thermal dissipation.
In addition to power switches, the module integrates several additional functions in a single package, including a current sensing shunt resistor, bypass capacitors for optimized switching, and an NTC thermistor for temperature monitoring. This level of integration simplifies system design, reduces component count, and supports more compact inverter implementations.
The device is housed in a 30 mm by 22.8 mm overmolded FlatPAK HC0 package with an electrically isolated exposed direct bonded copper (DBC) substrate. The overmolded structure enhances durability and supports reliable operation over a wide temperature range from -55°C to +175°C.
The module is designed to withstand harsh automotive operating conditions, particularly during repetitive power cycling, and meets AQG-324 automotive reliability requirements. The package architecture places signal pins and power terminals at different heights, enabling designers to separate signal and power printed circuit boards, thereby simplifying routing and supporting stacked board configurations for further space savings.
The VS-HOT200C080 is now available for sampling and in production quantities, with a standard lead time of 13 weeks. This device expands Vishay's portfolio of integrated automotive power solutions for the growing 48-volt electrified vehicle systems market.
