Driven by the dual forces of industrial automation and supply chain localization, the domestic substitution of core power devices has evolved from a backup option to a strategic imperative. Facing the stringent requirements for high efficiency, high current capability, and reliability in medium-voltage applications, finding a domestic alternative solution that is powerful, reliable in quality, and stable in supply has become a critical task for numerous OEMs and system integrators. When focusing on the classic 60V N-channel MOSFET from RENESAS IDT—the 2SK3714(0)-S12-AZ—the VBMB1615, launched by VBsemi, emerges as a formidable contender. It not only achieves precise performance alignment but also realizes a leap forward in key parameters based on advanced Trench technology, representing a value transformation from "usable" to "excellent," from "substitution" to "surpassing."
I. Parameter Comparison and Performance Leap: Fundamental Advantages Brought by Trench Technology
The 2SK3714(0)-S12-AZ has earned recognition in applications like power supplies, motor drives, and battery management due to its 60V voltage rating, 50A continuous drain current, and 13mΩ on-state resistance (at 10V, 25A). However, as system efficiency and power density demands increase, the inherent losses and current limitations of the device become bottlenecks.
1. Building on hardware compatibility with the same 60V drain-source voltage and similar package (TO220F for VBMB1615 vs. original package), the VBMB1615 achieves significant breakthroughs in key electrical characteristics through advanced Trench technology:
- Significantly Reduced On-Resistance: With VGS = 10V, the RDS(on) is as low as 10mΩ, a 23% reduction compared to the reference model. According to the conduction loss formula Pcond = I_D^2⋅RDS(on), losses are substantially lower at high current operating points, directly improving system efficiency, reducing temperature rise, and simplifying thermal design.
- Enhanced Current Handling: The continuous drain current rating increases to 70A, a 40% improvement, enabling higher load capacity and robustness in demanding applications.
- Optimized Switching Performance: Benefiting from Trench structure, the device features low gate charge and fast switching characteristics, reducing switching losses and supporting higher frequency operation for improved power density.
2. Robust Operational Range: With a gate-source voltage (VGS) of ±20V and a threshold voltage (Vth) of 2.5V, the VBMB1615 offers wide drive flexibility and stable performance under varying conditions, suitable for diverse circuit designs.
II. Deepening Application Scenarios: From Functional Replacement to System Upgrade
The VBMB1615 not only enables pin-to-pin or circuit-compatible replacement in existing applications of the 2SK3714(0)-S12-AZ but can also drive overall system performance improvements with its advantages:
1. Switching Power Supplies and DC-DC Converters
Lower conduction and switching losses enhance efficiency across load ranges, enabling compact designs and better thermal management for industrial and consumer power systems.
2. Motor Drives and Control Circuits
The high current capability and low RDS(on) support efficient motor control in appliances, automotive auxiliaries, and robotics, improving torque response and reliability.
3. Battery Management and Protection Systems
Suitable for discharge control and load switching in battery packs, the device’s low loss and high current rating extend battery life and ensure safe operation.
4. Industrial Automation and Energy Systems
In PLCs, inverters, and renewable energy applications, the 60V rating and robust performance contribute to system stability and efficiency upgrades.
III. Beyond Parameters: Reliability, Supply Chain Security, and Full-Lifecycle Value
Choosing the VBMB1615 is not only a technical decision but also a consideration of supply chain and commercial strategy:
1. Domestic Supply Chain Security
VBsemi possesses controllable capabilities across the entire chain from chip design to packaging and testing, ensuring stable supply, predictable lead times, and resilience against global disruptions, safeguarding production continuity for customers.
2. Comprehensive Cost Advantage

IV. Adaptation Recommendations and Replacement Path
For design projects currently using or planning to use the 2SK3714(0)-S12-AZ, the following steps are recommended for evaluation and switching:
1. Electrical Performance Verification
Compare key waveforms (switching speed, loss distribution, efficiency curves) under identical circuit conditions. Utilize the low RDS(on) and enhanced current capability of the VBMB1615 to adjust drive parameters for optimal performance.
2. Thermal Design and Mechanical Validation
Due to reduced conduction losses, thermal stress may be lower. Evaluate heat sink requirements and potential downsizing for cost and space savings.
3. Reliability Testing and System Validation
After completing electrical, thermal, and environmental tests in the lab, proceed to field or application-specific validation to ensure long-term stability and compatibility.
