In various medium-voltage, high-efficiency application scenarios such as power management modules, DC-DC converters, motor drives, battery protection circuits, and load switches, RENESAS's IDT 2SK2054-T1-AZ, with its balanced performance and compact packaging, has been a common choice for designers. However, facing challenges like extended international lead times, procurement complexity, and cost volatility, the need for a reliable, high-performance domestic alternative has become increasingly urgent. Responding to this market demand, VBsemi introduces the VBI1695 N-channel MOSFET, a pin-to-pin replacement designed to directly substitute the 2SK2054-T1-AZ, offering enhanced performance, full compatibility, and superior supply chain stability.
Superior Performance Parameters, Delivering Higher Power Density and Efficiency.
Engineered as a direct replacement for the 2SK2054-T1-AZ, the VBI1695 demonstrates significant improvements in key electrical specifications, providing stronger performance and greater design headroom:
The continuous drain current is boosted to 5.5A, substantially higher than the original 3A—an 83% increase. This allows the VBI1695 to handle higher current loads effortlessly, enabling more compact designs or supporting power upgrades in existing applications.
The on-state resistance is dramatically reduced to just 76mΩ (@10V gate drive), compared to the original 200mΩ (@10V, 1.5A). This 62% reduction in RDS(on) significantly lowers conduction losses, improves overall system efficiency, and minimizes heat generation.
The device maintains a 60V drain-source voltage rating, matching the original, ensuring suitability for the same application voltage ranges. It also supports a ±20V gate-source voltage, offering robust gate protection. The 1.7V typical threshold voltage ensures easy drive compatibility with common logic-level and standard driver ICs, facilitating seamless circuit integration.
Advanced Trench Technology, Ensuring Robust Reliability and Switching Performance.
The VBI1695 utilizes VBsemi's advanced Trench MOSFET technology. This process optimization achieves an excellent balance between low on-resistance and switching characteristics. The device features low gate charge and optimized internal capacitances, contributing to reduced switching losses and higher frequency operation capability—critical for efficient power conversion. It is designed for high reliability, undergoing rigorous testing including 100% automated final test and relevant reliability validations. The wide operating temperature range ensures stable performance across diverse environmental conditions, making it suitable for consumer, industrial, and automotive applications requiring long-term durability.
Drop-In Package Compatibility, Enabling Rapid and Risk-Free Design Transition.
A primary concern in component substitution is the engineering effort required for redesign. The VBI1695 eliminates this hurdle through full mechanical and footprint compatibility. It is offered in the industry-standard SOT-89 package, identical to the 2SK2054-T1-AZ in pinout, dimensions, and recommended PCB land pattern. This allows engineers to perform a direct replacement on existing boards without any layout modifications, thermal re-design, or mechanical adjustments. The substitution process is truly "plug-and-play," drastically reducing validation time and cost, accelerating time-to-market for end products.
Local Supply Chain and Support, Providing Assurance and Responsiveness.
Unlike imported components subject to logistical and geopolitical uncertainties, VBI1695 benefits from VBsemi's localized manufacturing and supply chain within China. This ensures stable production capacity, shorter and more predictable lead times, and cost advantages insulated from currency fluctuations. VBsemi provides comprehensive technical support, including detailed datasheets, application notes, and SPICE models. Our engineering team offers prompt assistance for substitution validation and application troubleshooting, overcoming the slow response times often associated with overseas suppliers.
From DC-DC converters and motor control circuits to battery management systems and various power switching functions, the VBI1695 stands as the superior domestic alternative to the RENESAS IDT 2SK2054-T1-AZ. With its compelling advantages of higher current capability, significantly lower on-resistance, complete package compatibility, and a secure local supply chain, it enables designers to enhance product performance while mitigating supply chain risks. Choosing VBI1695 is a strategic move towards design optimization, cost efficiency, and supply resilience.
