Introduction
Power MOSFETs serve as essential switches in modern electronic systems, controlling energy flow with precision. For years, international leaders like Infineon have set benchmarks with components such as the BSZ100N06LS3G. Yet, global supply chain disruptions and the push for technological self-reliance have made finding dependable, high-performance domestic alternatives a strategic priority. Represented by VBsemi's VBQF1615, local solutions now offer direct compatibility and competitive performance against established classics.
Part 1: Analysis of the Classic Component
Infineon's BSZ100N06LS3G is a 60V N-channel MOSFET featuring a continuous drain current of 20A and a low on-resistance of 10mΩ at 10V gate drive. Built with advanced trench technology, it delivers efficient power switching and thermal management in a compact PG-TDSON-8 package. This component is widely adopted in applications like DC-DC converters, motor drives, and power supplies, serving as a reliable choice for medium-power designs.
