In widespread high-voltage switching applications such as switch-mode power supplies, industrial controls, and motor drives, TOSHIBA's TK750A60F,S4X(S has been a popular choice for engineers due to its ease of gate control and low on-resistance. However, in the current climate of global supply chain volatility and extended lead times for imported components, reliance on this part presents growing challenges: uncertain availability, sensitivity to exchange rate fluctuations, and slower technical support. These factors increasingly impact production planning and cost efficiency for downstream manufacturers. In this context, domestic substitution is no longer just an alternative but a strategic necessity for ensuring supply chain resilience and competitive advantage.
Leveraging its proven expertise in power semiconductor design and manufacturing, VBsemi introduces the VBM16R10—an N-channel power MOSFET developed as a high-performance, pin-to-pin replacement for the TK750A60F,S4X(S. With upgraded electrical parameters, advanced planar technology, and full package compatibility, the VBM16R10 delivers a more robust, cost-effective, and locally supported solution for demanding high-voltage circuits.
Enhanced Electrical Parameters for Higher Efficiency and Reliability
Designed as a direct upgrade to the TK750A60F,S4X(S, the VBM16R10 offers meaningful improvements in key specifications, providing greater design margin and operational stability:
The drain-source voltage (VDS) is rated at 600V, matching the original part, ensuring suitability for the same application environments. The continuous drain current (ID) remains 10A, supporting equivalent current-handling capability.
A standout advantage is the significantly reduced on-state resistance: the VBM16R10 achieves just 500mΩ (at VGS=10V), compared to 620mΩ for the TK750A60F,S4X(S. This ~20% reduction in RDS(on) translates directly into lower conduction losses, improved energy efficiency, and reduced heat generation—critical for enhancing overall system reliability and thermal performance.
The device supports a gate-source voltage (VGS) of ±30V, offering robust protection against gate-side voltage spikes and noise in challenging electromagnetic environments. With a gate threshold voltage (Vth) of 3.5V, it ensures easy and reliable drive compatibility with common gate driver ICs, requiring no circuit modifications.
Advanced Planar Gate Technology for Robust Switching Performance
While the TK750A60F,S4X(S utilizes TOSHIBA’s process to achieve low on-resistance and good switching characteristics, the VBM16R10 employs an optimized planar gate structure that further enhances device ruggedness and switching reliability. The design minimizes internal capacitances, reducing switching losses and improving dv/dt immunity—key for high-frequency operation. Each device undergoes 100% avalanche energy testing and high-voltage screening, ensuring consistent performance under voltage transients and inductive switching conditions. With an operational temperature range from -55°C to 150°C and validation through extended reliability tests (including high-temperature/high-humidity aging), the VBM16R10 meets stringent requirements for industrial, automotive, and continuous-operation applications.
Full Package Compatibility for Seamless Drop-In Replacement
The VBM16R10 is offered in a TO-220 package that is mechanically and electrically identical to the TK750A60F,S4X(S. Pinout, footprint, and mounting dimensions are fully compatible, allowing engineers to replace the existing component without any PCB layout changes or thermal redesign. This plug-and-play approach eliminates re-engineering effort, reduces validation time to just 1–2 days, and avoids additional costs associated with board re-spins, mold modifications, or re-certification. Enterprises can swiftly adopt the VBM16R10 to de-risk their supply chain while maintaining product form, fit, and function.
Local Supply Chain Assurance and Responsive Technical Support
Unlike imported alternatives subject to extended lead times and logistical uncertainties, VBsemi manufactures the VBM16R10 within its fully controlled production facilities in China. Standard lead times are consistently within 2–3 weeks, with expedited options available for urgent needs. This localized supply eliminates exposure to international trade disruptions, currency volatility, and geopolitical uncertainties.
Furthermore, VBsemi provides dedicated local technical support, including comprehensive substitution reports, detailed datasheets, thermal guidance, and application notes. Engineers can access prompt, tailored assistance for circuit optimization or troubleshooting, ensuring a smooth and confident transition to the VBM16R10.
From switch-mode power supplies and industrial inverters to motor drives and LED lighting systems, the VBM16R10 stands out as a superior domestic alternative to the TK750A60F,S4X(S—combining better electrical performance, full compatibility, secure supply, and localized service. Adopting the VBM16R10 is more than a component swap; it is a strategic upgrade toward a more resilient, efficient, and competitive product supply chain.
