[SLKOR Semiconductor] Unlocking Efficiency: MMBF170L Medium Voltage MOSFET for Compact Power Designs
Over the past year, domestically produced SiC (Silicon Carbide) power devices have seen explosive growth, with a surge of manufacturers entering the field and launching automotive-grade SiC MOSFETs in a bid to break into the EV supply chain. Renowned for their high-temperature stability, fast switching speed, and low power losses, SiC power devices are rapidly becoming a cornerstone technology in the next generation of new energy vehicles.
Following this year’s post-Spring Festival price cuts in the EV market, advanced technologies like 800V platforms and SiC-based electric drive systems are now available in models priced under 200,000 RMB (approx. $27,000). This accessibility is accelerating the mainstream adoption of SiC, driving demand for more efficient, reliable power electronics.
As a next-generation semiconductor material, SiC significantly outperforms traditional silicon in power density, thermal tolerance, and efficiency — making it the ideal solution for electric vehicles. These advantages translate into longer driving range, faster charging, and more reliable power management, helping manufacturers meet growing consumer expectations for performance and sustainability.

In modern automotive transportation systems, medium-voltage MOSFETs play an essential role, particularly in electric and hybrid vehicles. These components are widely integrated into motor drive systems, battery management systems (BMS), and charging infrastructure, where they control current flow, enable efficient energy conversion, and enhance overall system performance.
By supporting high-efficiency power switching and thermal stability, medium-voltage MOSFETs are key to improving the efficiency, safety, and reliability of next-generation vehicles. As demand grows for greener, smarter transportation, these devices serve as a foundational technology for optimizing power delivery and system durability in EV and hybrid platforms.
The MMBF170L is a high-performance N-channel MOSFET designed for versatility and efficiency in a wide range of electronic applications. With a drain-source voltage of 60V, continuous drain current of 300mA, and low on-resistance of just 3Ω (@10V, 500mA), it ensures reliable and energy-efficient switching performance. Its low gate threshold voltage (2.5V @ 250µA) allows for ease of control in low-voltage systems.
Thanks to its compact size and solid electrical characteristics, the MMBF170L is ideally suited for power management circuits, motor control systems, EV charging stations, and auxiliary control units — providing a balance of stability, performance, and cost-efficiency in demanding environments.
The MMBF170L offers key features that make it highly effective for automotive and new energy vehicle (NEV) applications:
- High Drain-Source Voltage: Capable of withstanding the elevated voltage levels common in modern automotive electronic systems, ensuring safety and reliability.
- Strong Continuous Drain Current: Essential for electric motor control in EVs, where stable and efficient power switching directly impacts performance and responsiveness.
- Low On-State Resistance & Gate Threshold Voltage: These attributes help minimize power loss and heat generation during operation — translating to higher energy efficiency and improved thermal management.
- Precise Switching Performance: The low threshold voltage ensures accurate operation within the control circuit, supporting stable and predictable system behavior.
- Compact, Automotive-Ready Packaging: Designed to fit seamlessly into space-constrained automotive electronics environments, making it ideal for integration in advanced vehicle systems.
The MMBF170L is ideally suited for a wide range of applications in the fast-growing new energy vehicle (NEV) sector. It can be effectively integrated into DC-DC converters, battery management systems (BMS), and onboard chargers, ensuring efficient power conversion, energy control, and thermal performance.
In electric motor control circuits, the MMBF170L functions as a reliable switching device, supporting the high-efficiency demands of EV drive systems. With the global rollout of EV charging infrastructure accelerating, this device also plays a key role in charging stations and power management systems, enabling stable and efficient energy delivery for both fast and residential charging environments.
Beyond propulsion and charging, the MMBF170L is well-suited for auxiliary system control, such as vehicle air conditioning, infotainment, and safety systems — where compact design and energy efficiency are critical.
As global demand for environmentally friendly mobility grows, power semiconductor devices are becoming essential in boosting the performance, efficiency, and reliability of NEVs.
