Driven by the growing demand for supply chain resilience and component localization, identifying high-performance domestic alternatives for established power MOSFETs has become a strategic priority for designers. In applications requiring robust 600V switching capability, the TOSHIBA TK7A60W5,S5VX has been a common choice. Today, the VBMB16R07S from VBsemi emerges as a powerful domestic successor, offering not just a pin-to-pin replacement but a tangible performance enhancement, enabling a transition from simple substitution to system-level upgrade.
I. Parameter Comparison and Performance Enhancement: The Edge of Advanced SJ-Multi-EPI Technology
The TK7A60W5,S5VX is recognized for its 600V drain-source voltage, 7A continuous drain current, and 30W power dissipation in a TO-220F package. However, evolving efficiency and thermal management demands call for devices with lower losses.
1. Building on direct hardware compatibility with the same 600V VDS, 7A ID, and TO-220F package, the VBMB16R07S achieves key electrical improvements through its advanced SJ-Multi-EPI (Super Junction Multi-Epitaxial) technology:
Reduced Conduction Losses: With a typical RDS(on) of 650mΩ at VGS=10V, it offers optimized on-resistance, leading to lower conduction losses (Pcond = I_D^2 RDS(on)) compared to the reference part, improving efficiency and reducing operating temperature.
2. Robust Gate Drive & Reliability: Featuring a ±30V gate-source voltage rating and a 3.5V threshold (Vth), it ensures strong noise immunity and safe, reliable operation in demanding switching environments.
3. Technology Advantage: The SJ_Multi-EPI process provides an excellent balance of low on-resistance, fast switching capability, and high voltage ruggedness, contributing to overall system performance and longevity.
