In various medium-voltage, high-current application scenarios such as switch-mode power supplies, DC-DC converters, motor drives, battery management systems, and industrial control circuits, RENESAS IDT's 2SK3482-Z-AZ, with its robust performance and efficient switching characteristics, 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 growing challenges: extended lead times (often several months), cost volatility due to exchange rate fluctuations, and delayed technical support responses. These issues critically impact production schedules and cost efficiency for downstream enterprises. In this context, domestic substitution has evolved from an alternative to a necessity, serving as a strategic path to ensure supply chain security, reduce costs, and enhance core competitiveness.
Leveraging its deep expertise in power semiconductor technology, VBsemi introduces the VBE1104N N-channel power MOSFET through independent R&D. This product is precisely对标ed to the 2SK3482-Z-AZ, 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 high-quality solution for various medium-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance Margin, Adapting to Demanding Conditions.
Designed as a domestic alternative to the 2SK3482-Z-AZ, the VBE1104N achieves significant improvements in key electrical parameters, providing stronger performance guarantees:
First, the drain-source voltage remains at 100V, matching the original model, ensuring reliable operation in standard medium-voltage environments with adequate safety margins.
Second, the continuous drain current is increased to 40A, surpassing the original model's 36A—an 11% enhancement in current-carrying capacity. This allows effortless handling of higher power demands, whether in upgraded equipment or improved system stability at similar power levels.
Third, the on-state resistance is reduced to 30mΩ (@10V gate drive),优于 the 2SK3482-Z-AZ's 33mΩ (@10V). This lowers conduction losses, boosting overall system efficiency. In high-frequency switching applications, it significantly reduces heat generation, easing thermal design challenges and cutting energy costs.
Additionally, the VBE1104N supports a ±20V gate-source voltage, offering robust gate ESD and noise immunity, preventing unintended turn-on in noisy environments. The 1.8V gate threshold voltage balances drive convenience and switching reliability, seamlessly兼容 with mainstream driver ICs without circuit adjustments, further lowering substitution barriers.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The 2SK3482-Z-AZ relies on proven design for low on-resistance and switching efficiency. The VBE1104N employs industry-leading Trench technology, building upon the original's strengths while optimizing reliability. The device undergoes rigorous pre-shipment testing, including avalanche and high-voltage screening, demonstrating excellent surge energy handling. It reliably manages energy spikes during switching, reducing avalanche breakdown risks. Through optimized intrinsic capacitance design, it minimizes switching losses and enhances dv/dt tolerance, matching the 2SK3482-Z-AZ's application scenarios. Even under harsh conditions like high-frequency operation, it maintains stable performance with direct circuit replacement. Moreover, the VBE1104N features a wide operating temperature range, adapting to industrial高温 and outdoor extremes. Having passed extended reliability tests such as high-temperature/high-humidity aging, its failure rate is well below industry averages, ensuring long-term, uninterrupted operation—ideal for critical fields like automotive electronics, industrial automation, and renewable energy systems.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a key concern in domestic substitution is the R&D effort and time required. The VBE1104N addresses this through its package design. It uses a TO-252 package, identical to the 2SK3482-Z-AZ in pinout, spacing, dimensions, and thermal structure. Engineers need not alter PCB layouts or thermal designs, achieving "plug-and-play" replacement. This high compatibility reduces verification time—sample validation typically completes within 1-2 days—and avoids costs from PCB revisions or模具 adjustments. It also preserves original product certifications and外观, shortening supply chain cycles and enabling swift substitution to capture market opportunities.
