In various low-voltage, high-current application scenarios such as power management systems, motor drives, battery protection circuits, and DC-DC converters, TOSHIBA's TPN6R003NL,LQ, with its advanced trench technology and low on-resistance, has been a preferred choice for engineers worldwide. However, in the post-pandemic era, with intensified global supply chain disruptions and trade uncertainties, this imported component faces challenges such as unstable lead times, fluctuating procurement costs, and delayed technical support. These issues severely impact production schedules and cost control for downstream companies. Therefore, domestic substitution has become a necessity, crucial for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBQF1306 N-channel power MOSFET based on independent R&D. This product is precisely tailored as a domestic alternative to the TPN6R003NL,LQ, offering parameter upgrades, technological parity, and full package compatibility. It can directly replace the original without circuit modifications, providing a more stable, cost-effective, and locally supported solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Designed as a drop-in replacement for the TPN6R003NL,LQ, the VBQF1306 achieves significant improvements in key electrical parameters:
First, the continuous drain current is increased to 40A, substantially higher than the original model's 27A—a 48% enhancement in current-carrying capacity. This allows for handling higher power levels and improves system stability in demanding applications.
Second, the on-state resistance is reduced to 5mΩ (@10V gate drive), compared to the TPN6R003NL,LQ's 6mΩ (@10V, 13.5A). This lower RDS(on) minimizes conduction losses, boosting overall efficiency and reducing heat generation in high-current scenarios such as motor control and power switching.
Additionally, the VBQF1306 supports a ±20V gate-source voltage, offering robust gate ESD and noise immunity. The 1.7V gate threshold voltage ensures easy driving compatibility with mainstream driver ICs, eliminating the need for circuit adjustments and simplifying design integration.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The TPN6R003NL,LQ relies on trench technology for low on-resistance and fast switching. The VBQF1306 employs optimized trench technology, further improving device reliability and performance. It undergoes rigorous testing, including 100% avalanche and high-temperature screening, ensuring excellent durability under transient conditions such as inrush currents and load variations. The device features a wide operating temperature range from -55°C to 150°C, suitable for harsh environments like automotive electronics and industrial automation. Long-term reliability tests, such as high-temperature/high-humidity aging, confirm a low failure rate, making it ideal for critical applications where consistent operation is paramount.
Fully Compatible Package, Enabling Seamless Replacement.
The VBQF1306 uses a DFN8(3X3) package, identical to the TPN6R003NL,LQ in pinout, dimensions, and thermal characteristics. Engineers can directly replace the component without modifying PCB layouts or thermal designs, achieving "plug-and-play" substitution. This compatibility reduces verification time to 1-2 days, avoids redesign costs, and ensures quick integration into existing production lines, accelerating time-to-market for product updates.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Technical Support.
Compared to imported components, VBsemi leverages China's robust semiconductor industry chain, with modern production bases in Jiangsu and Guangdong. The VBQF1306 benefits from stable mass production, with lead times compressed to within 2 weeks and expedited delivery options for urgent orders. This mitigates risks from international supply chain volatility, tariff barriers, and geopolitical factors. Moreover, VBsemi provides dedicated technical support, offering comprehensive documentation, substitution reports, and application guides tailored to specific customer needs. The technical team responds within 24 hours to assist with any issues, ensuring a smooth transition and reducing downtime during replacement.
From power management and motor drives to battery-powered systems and DC-DC converters, the VBQF1306, with its core advantages of "superior parameters, enhanced reliability, package compatibility, controlled supply, and responsive service," has become the preferred domestic alternative to the TPN6R003NL,LQ. It has been successfully adopted by leading companies across industries, earning high market recognition. Choosing the VBQF1306 is not just a component replacement; it is a strategic move to secure supply chains, optimize costs, and boost product competitiveness—all without R&D risks, while enjoying better performance, stable supply, and local support.
