In various automotive power application scenarios such as electric vehicle powertrains, battery management systems, DC-DC converters, and motor drives, Infineon's IPC100N04S5L-2R6, with its AEC-Q101 qualification, logic-level gate drive, and 100% avalanche testing, has long been a significant choice for engineers worldwide. However, against the backdrop of global supply chain disruptions and trade uncertainties, this imported component faces challenges: unstable lead times, procurement costs affected by exchange rates, and slow technical support. These issues constrain production schedules and cost control for downstream companies. Given this demand, domestic substitution has become a necessity for ensuring supply chain security and enhancing competitiveness.
VBsemi, with years of expertise in power semiconductors, launches the VBQA1402 N-channel power MOSFET based on independent R&D. This product directly targets the IPC100N04S5L-2R6, offering core advantages of parameter upgrades, technological parity, and package compatibility. It serves as a drop-in replacement without circuit modifications, providing a more stable, cost-effective, and locally supported solution for automotive power systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the IPC100N04S5L-2R6, the VBQA1402 achieves leapfrog improvements in key electrical parameters:
First, the continuous drain current is increased to 120A, significantly higher than the original 100A—a 20% enhancement. This allows handling higher power loads, improving system robustness.
Second, the on-state resistance is as low as 2mΩ (@10V gate drive), superior to the original 2.6mΩ—a 23% reduction. This lowers conduction losses, improving efficiency and reducing heat generation.
The drain-source voltage remains 40V, matching the original for automotive applications. The gate-source voltage supports ±20V, offering strong ESD and noise immunity. The 3V gate threshold voltage ensures compatibility with logic-level drivers, facilitating easy integration.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The IPC100N04S5L-2R6 relies on Infineon's advanced process for low RDS(on) and high reliability. The VBQA1402 employs state-of-the-art Trench technology, optimizing switching performance and reliability. The device undergoes 100% avalanche testing, ensuring robustness against voltage surges. With an operating temperature range up to 175°C, it meets automotive-grade requirements. It has passed rigorous reliability tests, including high-temperature and humidity aging, making it suitable for harsh automotive environments.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, replacement cost and time are critical. The VBQA1402 addresses this with its DFN8(5X6) package, which is pin-to-pin compatible with the original part. Engineers need not modify PCB layouts or thermal designs, achieving drop-in replacement. This reduces verification time to 1-2 days, avoids redesign costs, and shortens the supply chain cycle.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components, VBsemi leverages China's semiconductor industry chain, with production bases in Jiangsu and Guangdong. The VBQA1402 has a standard lead time within 2 weeks, with emergency orders available for 72-hour delivery. This mitigates risks from international logistics and tariffs. As a local brand, VBsemi provides dedicated technical support: comprehensive documentation, substitution reports, datasheets, and application guides. The technical team offers 24-hour response for any issues, ensuring a smooth substitution process.
From automotive powertrains and DC-DC converters to motor drives and battery systems, the VBQA1402, with its "superior parameters, enhanced reliability, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the IPC100N04S5L-2R6. It has been adopted by leading automotive companies, gaining market recognition. Choosing VBQA1402 is not just a component replacement; it is a strategic move to secure supply chains, optimize costs, and boost competitiveness—without R&D risks, while enjoying better performance, stable supply, and local support.
