In various low-voltage, high-current application scenarios such as power management systems, motor drives, battery protection circuits, portable devices, and automotive electronics, RENESAS IDT's RQM2201DNS#P0, with its dual N-channel configuration and efficient switching performance, has been a trusted choice for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces significant challenges: prolonged lead times (often extending to several months), procurement costs vulnerable to exchange rate swings, and delayed technical support. These issues increasingly hinder downstream companies' production efficiency and cost optimization. Against this backdrop, domestic substitution has evolved from an "alternative" to a "strategic imperative," offering a critical path for enterprises to secure supply chains, reduce expenses, and enhance competitiveness.
Leveraging years of expertise in power semiconductor innovation, VBsemi introduces the VBQF3638 dual N-channel power MOSFET through independent R&D. This product is meticulously designed to match and surpass the RQM2201DNS#P0, delivering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a drop-in replacement without circuit modifications, providing a more robust, cost-effective, and locally supported solution for low-voltage electronic systems.
Comprehensive Parameter Advancement, Enhanced Performance Margins, Adapting to Demanding Low-Voltage Conditions.
Tailored as a domestic alternative to the RQM2201DNS#P0, the VBQF3638 achieves significant, leapfrog improvements in key electrical parameters, ensuring superior performance in low-voltage applications:
First, the continuous drain current is dramatically increased to 25A, a substantial 1150% enhancement over the original model's 2A. This massive boost in current-carrying capability enables effortless handling of higher power loads, whether upgrading existing designs or improving system stability in high-current scenarios like motor drives or power supplies.
Second, the on-state resistance is drastically reduced to 28mΩ (@10V gate drive), compared to the RQM2201DNS#P0's 225mΩ (@4.5V, 1A). This represents a remarkable decrease in conduction losses, directly translating to higher overall efficiency and reduced heat generation. In high-frequency switching applications, it minimizes thermal stress, lowering cooling system demands and energy costs.
Additionally, the VBQF3638 supports a ±20V gate-source voltage, offering robust gate ESD and noise immunity to prevent unintended turn-on in noisy environments. The 1.7V gate threshold voltage balances drive ease and switching reliability, seamlessly interfacing with mainstream driver ICs without drive circuit adjustments, further simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Reinforced.
The RQM2201DNS#P0 relies on proven MOSFET design for low on-resistance and switching efficiency. The VBQF3638 employs industry-leading Trench technology, building upon the original model's strengths while optimizing device reliability across multiple dimensions. Through refined fabrication processes, the device exhibits excellent switching characteristics, low gate charge, and high dv/dt tolerance. It undergoes rigorous pre-shipment testing, including 100% electrical screening, ensuring consistent performance under transient conditions. The optimized internal capacitance structure reduces switching losses and enhances durability, making it ideal for fast-switching applications. Moreover, the VBQF3638 operates over a wide temperature range from -55°C to 150°C, adapting to harsh environments like automotive underhood or industrial settings. It has passed extended reliability tests, including high-temperature aging and humidity resistance, with a failure rate well below industry averages, providing dependable long-term operation for critical applications such as automotive systems, industrial controls, and consumer electronics.
Fully Compatible Package, Enabling "Seamless, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a key concern in domestic substitution is the engineering effort and time required. The VBQF3638 addresses this through its package design. The device uses a DFN8(3X3)-B package, which is fully compatible with the RQM2201DNS#P0 in terms of pinout, pin spacing, and footprint dimensions. Engineers can directly replace the original component without altering PCB layouts or thermal management designs, achieving true "plug-and-play" convenience. This high compatibility reduces substitution verification time to as little as 1-2 days for sample testing, eliminates costs associated with PCB revisions or tooling changes, and preserves original product certifications and外观. By streamlining the supply chain, it helps enterprises rapidly adopt domestic alternatives and capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Unlike imported components affected by international logistics, trade policies, and currency fluctuations, VBsemi leverages China's robust semiconductor ecosystem, with modern production bases and R&D centers in Jiangsu, Guangdong, and beyond. This ensures full-process control and stable mass production for the VBQF3638. Current lead times are compressed to under 2 weeks, with expedited orders enabling 72-hour delivery, mitigating risks from supply chain volatility, tariffs, or geopolitics.
