In various low-voltage, high-current application scenarios such as DC-DC converters, motor drives, battery protection circuits, power tools, and portable electronics, Microchip's HAT2168H-EL-E, with its efficient switching performance and compact design, has been a key component for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported part has revealed significant pain points: unpredictable lead times (often extending to months), procurement costs vulnerable to currency fluctuations, and delayed technical support. These challenges severely impact production schedules and cost management for downstream companies. Consequently, domestic substitution has evolved from an "option" to a "necessity," becoming a critical strategy for ensuring supply chain security, reducing costs, and enhancing competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBED1303 N-channel MOSFET based on independent R&D. This product is precisely tailored to replace the HAT2168H-EL-E, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported solution for low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance, Adapting to Demanding Conditions.
Designed as a domestic alternative to the HAT2168H-EL-E, the VBED1303 achieves significant improvements in key electrical parameters, providing robust performance for high-current applications:
First, the drain-source voltage remains at 30V, matching the original model, ensuring compatibility in low-voltage circuits while offering reliable operation in environments with voltage variations.
Second, the continuous drain current is dramatically increased to 90A, tripling the original model's 30A—a 200% enhancement in current-carrying capability. This enables effortless handling of higher power demands, whether upgrading existing designs or improving system stability at similar power levels.
Third, the on-state resistance is as low as 2.8mΩ (@10V gate drive), substantially superior to the HAT2168H-EL-E's 13.5mΩ (@4.5V, 15A). This reduction minimizes conduction losses, boosting overall efficiency and reducing heat generation—critical for high-frequency switching applications, thereby lowering cooling system requirements and energy costs.
Additionally, the VBED1303 supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity to prevent unintended turn-on in noisy environments. The 0.8V gate threshold voltage balances drive convenience and switching reliability, seamlessly matching mainstream driver ICs without drive circuit adjustments, further simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The HAT2168H-EL-E relies on its design for low on-resistance and efficient switching. The VBED1303 employs industry-leading Trench technology, building upon the original model's strengths while optimizing reliability. The device undergoes rigorous pre-shipment testing, including avalanche and high-current screening, ensuring excellent robustness against energy surges during switching. Through optimized intrinsic capacitance design, it reduces charge/discharge losses and enhances dv/dt tolerance, maintaining stable operation under high-frequency switching or transient conditions. Furthermore, the VBED1303 features an extended operating temperature range and has passed long-term reliability tests such as high-temperature/high-humidity aging, with a failure rate well below industry averages. This makes it ideal for critical applications requiring durability, like automotive systems, industrial controls, and consumer electronics.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, a major concern in domestic substitution is the R&D effort and time involved. The VBED1303 addresses this through its package design. It uses an LFPAK56 package, identical to the HAT2168H-EL-E in pinout, pin spacing, dimensions, and thermal pad structure. Engineers can replace the component without altering PCB layouts or thermal designs, achieving a true "drop-in" solution. This compatibility reduces verification time to 1-2 days for samples, avoids costs from PCB revisions or mold changes, and eliminates the need for re-certification or外观 adjustments. It streamlines the supply chain, helping companies quickly adopt domestic alternatives and capture market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components with unstable supply chains affected by logistics, trade policies, and exchange rates, VBsemi leverages China's robust semiconductor ecosystem, with modern production bases in Jiangsu and Guangdong. This enables full-process R&D and stable mass production of the VBED1303. Standard lead times are compressed to under 2 weeks, with emergency orders supporting 72-hour fast delivery, mitigating risks from international volatility, tariffs, or geopolitics. As a local brand, VBsemi provides a professional technical support team offering "one-on-one" customized services: comprehensive documentation (substitution reports, datasheets, thermal guides, application circuits), tailored selection advice, and circuit optimization. For any substitution issues, the team responds within 24 hours for on-site or remote resolution, eliminating the slow support and high communication costs of imported parts.
From DC-DC converters and motor drives to battery management systems and power tools; from portable electronics and automotive applications to industrial automation and renewable energy systems, the VBED1303—with its core advantages of "superior parameters, enhanced performance, package compatibility, controllable supply, and attentive service"—has become the preferred domestic alternative to the HAT2168H-EL-E. It has gained adoption in leading companies across multiple industries, earning high market recognition. Choosing the VBED1303 is not just a component swap; it is a strategic move for upgrading supply chain security, optimizing costs, and boosting product competitiveness—requiring no R&D modification risks while delivering better performance, stable supply, and responsive support.
