Introduction
Power MOSFETs serve as critical switches managing energy flow in modern electronics. For decades, international giants like TOSHIBA have set industry standards with proven components such as the TK35N65W,S1F. However, global supply chain uncertainties and the drive for technological self-reliance have made finding dependable, high-performance domestic alternatives a strategic imperative. Represented by VBsemi’s VBP165R36S, domestic solutions are now achieving direct对标and even surpassing international benchmarks.
Part 1: Analysis of the Classic Component
TOSHIBA’s TK35N65W,S1F is a high-voltage MOSFET (650V, 35A) designed for robust power handling, with a dissipation capability of 270W. It employs advanced technology to balance voltage endurance and current capacity, making it a preferred choice in high-power applications like industrial motor drives, power supplies, and energy systems. Its reliability and performance have established it as a go-to component in many designs.
