In various automotive and high-reliability application scenarios such as automotive systems, power management, and other demanding environments, Infineon's AUIRF7103QTR, with its cellular design and advanced processing technology, has been a significant choice for engineers worldwide. However, in the post-pandemic era with global supply chain disruptions, this imported component faces issues like unstable lead times, cost fluctuations, and slow technical support. These challenges constrain production schedules and cost control. Given this, domestic substitution has become a necessity for ensuring supply chain security and enhancing competitiveness.
VBsemi, with deep expertise in power semiconductors, introduces the VBA3610N dual N-channel MOSFET based on independent R&D. This product precisely matches the AUIRF7103QTR, offering parameter upgrades, technological parity, and full package compatibility. It can be directly replaced without circuit modifications, providing a stable, cost-effective, and locally supported solution.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the AUIRF7103QTR, the VBA3610N achieves leapfrog improvements in key electrical parameters:
Firstly, the drain-source voltage is increased to 60V, 10V higher than the original model's 50V—a 20% improvement. This provides a safer margin in automotive environments with voltage fluctuations.
Secondly, the continuous drain current is increased to 4A, surpassing the original model's 3A—a 33% enhancement in current-carrying capability, enabling higher power applications.
Thirdly, the on-state resistance is as low as 110mΩ (@10V gate drive), superior to the AUIRF7103QTR's 130mΩ. This reduces conduction losses, improving efficiency and reducing heat generation.
Additionally, the VBA3610N supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity. The 1.9V gate threshold voltage balances driving convenience and reliability, matching mainstream driver ICs without adjustments.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the AUIRF7103QTR lies in its cellular design for low on-resistance and fast switching. The VBA3610N employs advanced Trench technology, optimizing device reliability. It undergoes rigorous testing, including avalanche and high-temperature screening, ensuring robust performance in harsh conditions. The optimized capacitance structure reduces switching losses and enhances dv/dt tolerance, suitable for high-frequency applications. With an operating temperature range of -55°C to 150°C, it adapts to automotive and industrial environments. Long-term reliability tests confirm low failure rates, ideal for critical applications like automotive electronics and industrial control.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
The VBA3610N uses an SOP8 package, identical to the AUIRF7103QTR in pinout, dimensions, and layout. Engineers can achieve "plug-and-play" replacement without PCB modifications or thermal redesign. This reduces verification time to 1-2 days, avoids extra costs, and ensures seamless integration, shortening the supply chain cycle.
