In the pursuit of robust and diversified electronics supply chains, engineers globally are seeking reliable, high-specification alternatives to core components. If you are considering the high-performance N-channel MOSFET, Infineon's BSC093N15NS5, evaluate the advanced Chinese-designed alternative: VBsemi's VBGQA1151N.
This represents a strategic, performance-matched alternative, delivering key electrical characteristics while providing the stability and competitive advantages of a modern, diversified supply source.
Engineered for Demanding Applications
The Infineon BSC093N15NS5 is a benchmark in its class, featuring a 150V drain-source voltage, 87A continuous current, and an exceptionally low 9.3mΩ RDS(on) in the TDSON-8 package. It is renowned for its excellent FOM and low Qrr, making it ideal for high-frequency switching.
The VBsemi VBGQA1151N is designed to meet these challenges in a compact DFN8(5x6) footprint. Built on the same 150V Vdss foundation, it offers a robust 70A continuous drain current and a low 13.5mΩ RDS(on) at 10V gate drive. This combination ensures strong performance in high-current paths.
Key Performance Alignment & Strategic Advantages
Voltage & Current Robustness: Both MOSFETs are rated for 150V, suitable for similar application spaces. The VBGQA1151N's 70A Id provides substantial current-handling capability for demanding circuits.
Optimized for Efficiency: While the RDS(on) figures differ, the VBGQA1151N's 13.5mΩ remains highly competitive, ensuring low conduction losses. Its SGT (Shielded Gate Trench) technology contributes to good switching performance and reliability.
Package & Integration: The DFN8(5x6) package of the VBGQA1151N offers a compact, surface-mount solution, facilitating high-power-density designs.
Supply Chain Resilience: Sourcing from VBsemi provides a qualified alternative source, mitigating risks associated with single-supplier dependency and market volatility.
Cost-Effectiveness: It offers a value-competitive solution without compromising on the core performance required for challenging applications.
