In application scenarios demanding high-voltage switching and high-current handling, such as switch-mode power supplies, motor drives, and industrial inverters, TOSHIBA's TK16A60W (S4VX), with its Super Junction structure (DTMOS), low on-resistance, and ease of gate control, has been a widely adopted choice for engineers. However, navigating the complexities of global supply chains and seeking cost optimization have made domestic alternatives a strategic imperative for ensuring production stability and enhancing competitiveness.
VBsemi, leveraging its expertise in power semiconductors, introduces the VBMB16R15S N-channel MOSFET. This product is precisely engineered as a direct, pin-to-pin alternative to the TK16A60W(S4VX), offering core advantages of parameter matching, advanced technology, and full package compatibility. It enables a seamless replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution.
Precise Parameter Matching and Robust Performance for Demanding Designs
Tailored as the domestic counterpart to the TK16A60W, the VBMB16R15S provides excellent parameter alignment and reliability for high-current applications:
Its drain-source voltage is rated at 600V, fully matching the original component's requirement, ensuring safe operation in standard high-voltage environments. The continuous drain current is a robust 15A, closely matching the original's 15.8A, guaranteeing ample current-carrying capacity for demanding circuits like switch-mode regulators and motor drives.
The device features a gate threshold voltage (Vth) of 3.5V, well within the enhanced mode range (2.7V - 3.7V) of the TK16A60W, ensuring easy and reliable gate control and compatibility with mainstream driver ICs. Furthermore, it supports a ±30V gate-source voltage, offering superior protection against gate-side ESD and noise, enhancing system robustness in complex EMI environments.
Advanced Super Junction Multi-EPI Technology, Ensuring Superior Reliability
The TK16A60W utilizes DTMOS Super Junction technology for low resistance. The VBMB16R15S employs VBsemi's advanced SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology. This process achieves an excellent balance between low conduction loss and high switching performance. While providing the low on-resistance crucial for efficiency, its optimized internal structure enhances dv/dt capability and switching ruggedness.
The VBMB16R15S is designed for maximum reliability, featuring an operating temperature range from -55°C to 150°C. It undergoes rigorous reliability testing, including high-temperature and high-humidity bias tests, ensuring stable, long-term operation even in harsh industrial environments. This makes it an ideal, drop-in replacement for the original part in critical applications.
Fully Compatible TO-220F Package, Enabling Immediate "Plug-and-Play" Replacement
A key concern in component substitution is redesign effort. The VBMB16R15S eliminates this hurdle entirely. It comes in a standard TO-220F package, which is physically and dimensionally identical to the package of the TK16A60W(S4VX). The pinout, footprint, and mounting hole positions are exactly the same.
This complete package compatibility allows engineers to replace the component on existing PCB layouts without any changes to the board design, heatsink, or mechanical assembly. It enables a true "plug-and-play" substitution, dramatically reducing validation time, eliminating redesign costs, and accelerating time-to-market for your product upgrades.
Local Supply Chain Strength and Proactive Technical Support
Compared to the uncertainties of international procurement—long lead times, cost volatility, and logistical delays—VBsemi offers the security of a localized supply chain. With modern manufacturing facilities, the VBMB16R15S benefits from stable, high-volume production and significantly shorter, more predictable lead times.
