In various low-voltage, high-current application scenarios such as power switches, load switches, battery management systems, and DC-DC converters, ROHM's RQ3E075ATTB, with its low on-resistance, high-power small-size HSMT8 package, and compliance with RoHS and halogen-free standards, has been a popular choice for engineers worldwide. However, in the post-pandemic era with global supply chain disruptions and trade frictions, this imported component faces issues like unstable lead times, procurement cost fluctuations due to exchange rates, and delayed technical support, which hinder production schedules and cost control for downstream companies. Given this demand, domestic substitution has become a necessity for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, with years of expertise in power semiconductors, introduces the VBQF2317 P-channel power MOSFET based on independent R&D. This product directly对标 the RQ3E075ATTB, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a drop-in replacement without circuit modifications, providing a more stable, cost-effective, and locally supported solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the RQ3E075ATTB, the VBQF2317 achieves across-the-board improvements in key electrical parameters:
Firstly, the drain-source voltage is maintained at 30V, matching the original model, ensuring compatibility in low-voltage applications.
Secondly, the continuous drain current is increased to 24A, significantly surpassing the original model's 18A—a 33.3% enhancement in current-carrying capability. This allows for handling higher power levels and improving system stability.
Thirdly, the on-state resistance is as low as 17mΩ (@10V gate drive), superior to the RQ3E075ATTB's 23mΩ (@10V,7.5A). This reduction in conduction losses improves efficiency and reduces heat generation, easing thermal design challenges.
Additionally, the VBQF2317 supports a ±20V gate-source voltage, offering robust gate ESD and noise immunity. The -1.7V gate threshold voltage balances drive convenience and switching reliability, compatible with mainstream driver ICs without circuit adjustments.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The RQ3E075ATTB excels in low on-resistance and compact packaging. The VBQF2317 employs advanced Trench technology, optimizing device reliability and performance. It undergoes rigorous testing, including 100% avalanche testing and high-voltage screening, ensuring excellent avalanche energy handling and reducing failure risks. The optimized capacitance structure minimizes switching losses and enhances dv/dt tolerance. With an operating temperature range of -55°C to 150°C, it adapts to harsh environments. Reliability tests such as high-temperature/high-humidity aging verify long-term stability, making it suitable for critical applications like automotive, industrial control, and portable devices.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
The VBQF2317 addresses replacement concerns through its package design. It uses a DFN8(3x3) package, which is compatible with the RQ3E075ATTB's HSMT8 package in terms of pinout, dimensions, and thermal characteristics. Engineers can directly replace it without modifying PCB layout or thermal design, achieving plug-and-play convenience. This compatibility reduces verification time to 1-2 days, avoids PCB revisions and mold adjustments, and shortens the supply chain cycle, enabling quick substitution.
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 VBQF2317 is independently研发 and mass-produced, with lead times compressed to within 2 weeks and emergency orders delivered within 72 hours. This mitigates risks from supply chain volatility, tariffs, and geopolitics. As a local brand, VBsemi provides professional technical support: comprehensive documentation, substitution验证 reports, datasheets, thermal guides, and application circuits. The technical team offers 24-hour rapid response for any issues, resolving pain points of slow support and high communication costs.
From power switches and load switches to battery management and DC-DC converters, the VBQF2317, with its core advantages of "superior parameters, stable performance, package compatibility, controllable supply, and attentive service," has become the preferred domestic alternative to the RQ3E075ATTB. It has been adopted by leading companies in various industries. Choosing VBQF2317 is not just a component replacement but a step towards securing supply chains, optimizing costs, and enhancing competitiveness—without R&D risks, while enjoying better performance, stable supply, and convenient support.
