In various compact and high-efficiency application scenarios such as power management systems, motor drives, battery protection circuits, and portable electronic devices, MCC's MCQ4828A-TP, with its dual N-channel configuration and low on-resistance, has been a popular choice for engineers worldwide. However, in the post-pandemic era, this imported component has gradually exposed pain points like unstable lead times, procurement costs affected by exchange rate fluctuations, and slow technical support responses. These issues constrain production schedules and cost control for downstream companies. Given this demand, domestic substitution has become a necessity, ensuring supply chain security and enhancing core competitiveness.
VBsemi, with deep expertise in power semiconductors, launches the VBA3638 dual N-channel MOSFET based on independent R&D. This product precisely对标es the MCQ4828A-TP, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without circuit modifications, providing a more stable, cost-effective, and locally attuned solution.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the MCQ4828A-TP, the VBA3638 achieves significant improvements in key electrical parameters:
Firstly, the drain-source voltage is 60V, matching the original model, but with a drastically lower on-state resistance. The VBA3638 offers an RDS(on) of only 28mΩ at VGS=10V, significantly reducing conduction losses and improving overall efficiency compared to the original design.
Secondly, the continuous drain current is increased to 7A, providing higher current-carrying capability for more powerful and robust circuit designs.
Thirdly, the gate threshold voltage is lowered to 1.7V, compared to the original's 3V, enabling easier drive with lower gate voltage and enhancing switching performance in low-voltage applications.
Additionally, the VBA3638 supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity. The optimized threshold voltage design balances driving convenience and reliability, seamlessly compatible with mainstream driver ICs without requiring circuit adjustments.
Enhanced with Advanced Trench Technology, Reliability and Stability Upgraded.
The VBA3638 employs advanced Trench technology, delivering low on-resistance and fast switching characteristics. It undergoes rigorous testing including 100% avalanche testing and high-temperature screening, ensuring excellent reliability under harsh conditions. The device features an operating temperature range of -55°C to 150°C, adapting to industrial and outdoor environments. Long-term reliability tests such as high-temperature/high-humidity aging confirm a low failure rate, suitable for critical applications like automotive electronics, industrial control, and consumer devices.
Fully Compatible Package, Enabling Seamless Replacement.
The VBA3638 uses an SOP8 package, identical to the MCQ4828A-TP in pinout, dimensions, and footprint. Engineers can directly replace the original component without PCB layout changes or thermal design adjustments, 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.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Compared to imported components, VBsemi leverages China's robust semiconductor产业链, with modern production bases in Jiangsu and Guangdong, enabling stable mass production of the VBA3638. Lead times are compressed to within 2 weeks, with emergency orders available for 72-hour delivery, mitigating risks from international supply chain disruptions. As a local brand, VBsemi provides dedicated technical support, offering comprehensive documentation, substitution验证 reports, and application guidance. The technical team responds within 24 hours for any issues, ensuring a smooth substitution process.
From power management and motor drives to battery protection and portable devices, the VBA3638, with its "superior parameters, enhanced reliability, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the MCQ4828A-TP. It has been adopted by leading companies across industries, gaining market recognition. Choosing the VBA3638 is not just a component replacement; it is a strategic move to upgrade supply chain security, optimize costs, and improve product competitiveness—without R&D risks, while enjoying better performance, stable supply, and local support.
