In high-voltage, high-power application scenarios such as industrial motor drives, solar inverters, electric vehicle charging systems, and UPS, TOSHIBA's TW030N120C,S1F, with its high voltage tolerance, robust current capability, and reliable performance, has been a preferred component for engineers globally. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported part has revealed persistent pain points: extended lead times (often exceeding 4-6 months), procurement costs vulnerable to currency fluctuations, and delayed technical support. These challenges increasingly hinder production schedules and cost optimization for downstream enterprises. Against this backdrop, domestic substitution has evolved from an "alternative" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBP112MC60 SiC MOSFET through independent R&D. This product is meticulously designed as a direct alternative to the TW030N120C,S1F, offering core advantages of parameter parity, technological advancement, and full package compatibility. It enables seamless replacement without circuit modifications, delivering a more efficient, cost-effective, and locally supported solution for high-voltage electronic systems.
Parameter Parity with SiC Technology Edge, Enabling Superior Performance in Demanding Conditions.
Tailored as a domestic drop-in replacement for the TW030N120C,S1F, the VBP112MC60 achieves key electrical parameter equivalence while leveraging silicon carbide (SiC) technology for enhanced efficiency and reliability:
First, the drain-source voltage is maintained at 1200V, matching the original model's rating. This ensures sufficient safety margins in applications with high voltage spikes and fluctuations, such as industrial grids and renewable energy systems.
Second, the continuous drain current is rated at 40A. While numerically lower than the original 60A, the VBP112MC60's SiC technology enables significantly lower switching losses and higher operating frequencies. This allows for improved system efficiency and thermal performance, often resulting in comparable or better real-world current-handling capability in optimized designs.
Third, the on-state resistance is 40mΩ (@18V gate drive), identical to the TW030N120C,S1F's 40mΩ. This ensures minimal conduction losses, contributing to higher overall system efficiency and reduced heat generation.
Additionally, the VBP112MC60 supports a gate-source voltage range of -10V to +22V, offering enhanced gate noise immunity and ESD protection for reliable operation in harsh electromagnetic environments. The gate threshold voltage of 2-4V ensures compatibility with mainstream driver ICs, simplifying drive circuit design and facilitating easy substitution.
Advanced SiC Technology for Enhanced Reliability and Switching Performance.
The TW030N120C,S1F relies on traditional silicon-based technology for high-voltage operation. In contrast, the VBP112MC60 employs state-of-the-art SiC-S (silicon carbide) technology, delivering leapfrog improvements in switching characteristics and reliability. SiC's inherent material advantages enable faster switching speeds, lower switching losses, and superior high-temperature operation. The device undergoes rigorous avalanche testing and high-voltage screening, ensuring robust performance during transient overvoltage events. Its optimized capacitance structure reduces charge/discharge losses, further improving dv/dt tolerance and efficiency in high-frequency applications. With an operating temperature range up to 150°C, the VBP112MC60 excels in demanding environments like industrial heating, outdoor installations, and automotive systems. It has passed extended reliability tests, including high-temperature/high-humidity aging, resulting in a failure rate well below industry averages—ideal for critical applications in medical equipment, power infrastructure, and transportation.
Fully Compatible Package for Direct, Risk-Free Replacement.
For downstream enterprises, replacement complexity is a primary concern. The VBP112MC60 eliminates this through its package design. The device uses a TO-247 package, which is fully compatible with the TW030N120C,S1F in pinout, pin spacing, dimensions, and heatsink mounting. Engineers can achieve "plug-and-play" substitution without altering PCB layouts or thermal management designs. This compatibility drastically reduces verification time—sample validation typically completes within 1-2 days—and avoids costs associated with PCB redesigns, mold adjustments, or re-certification. It enables quick supply chain transitions, allowing enterprises to rapidly adopt domestic alternatives and seize market opportunities.
Localized Supply Chain and Responsive Technical Support for Peace of Mind.
