SLKOR's MMBF170L: Elevating Your Circuit Designs with High-Performance Medium Voltage MOSFETs
Over the past year, domestically produced SiC (Silicon Carbide) power devices have experienced explosive growth, with a wave of manufacturers announcing their entry into the market or launching automotive-grade SiC MOSFET products in hopes of securing a place in the automotive supply chain. Celebrated for their exceptional high-temperature tolerance, high-frequency performance, and low switching losses, SiC power devices have become a cornerstone technology for next-generation new energy vehicles (NEVs).
Following a fresh round of price cuts for NEVs after this year’s Spring Festival, advanced 800V platforms and SiC electric drive systems are now entering the market at price points under 200,000 yuan, accelerating mass adoption. As the NEV market continues its rapid ascent, the demand for highly efficient, durable, and reliable power devices has never been greater — positioning SiC technology at the heart of this dynamic transformation.
As a next-generation semiconductor material, SiC (Silicon Carbide) power devices deliver clear advantages over traditional silicon solutions — offering superior power density, exceptional temperature stability, and faster switching speeds. These attributes make SiC the ideal choice for electric vehicles, enabling greater energy efficiency, more reliable power management, and unlocking new possibilities for enhanced performance and extended driving range.
The rapid expansion of the new energy vehicle (NEV) market, coupled with aggressive price competition, is accelerating the adoption of SiC technology across a broader range of models. SiC power devices are poised to play a pivotal role in driving technological breakthroughs within the NEV sector and advancing the global transition toward clean, sustainable transportation.

The MMBF170L is a high-performance N-channel MOSFET recognized for its balanced and reliable specifications. It offers a drain-source voltage of 60V, continuous drain current of 300mA, low on-resistance of 3Ω (at 10V, 500mA), and a low threshold voltage of just 2.5V (at 250μA). These features make it an excellent choice for a wide range of applications, including power management systems, motor drive controls, EV charging stations, and auxiliary electronic control units — where efficiency, precision, and compact design are crucial.
First, it offers a high drain-source voltage, making it well-suited to handle the elevated voltages commonly found in automotive electronic systems. Second, its continuous drain current capability is vital for electric motor control applications. In new energy vehicles, where the electric motor serves as the core power source, high-performance switching components are essential for achieving efficient, responsive control — and this MOSFET meets those demands effortlessly.
Additionally, its low on-state resistance and reduced threshold voltage help minimize power consumption and thermal losses during operation, improving overall energy efficiency. The lower threshold voltage also ensures more accurate, reliable performance within sensitive control circuits. Finally, its compact, thermally resilient package makes it an excellent fit for space-constrained automotive electronic systems, contributing to streamlined designs without compromising on durability or performance.
The MMBF170L holds strong potential in the rapidly growing new energy vehicle (NEV) market. It’s a versatile solution ideal for use in DC-DC converters, battery management systems (BMS), and onboard chargers — enabling efficient, stable power conversion and energy management. Additionally, it serves as a reliable switching component in electric motor control circuits, where performance, efficiency, and responsiveness are critical.
As global EV charging infrastructure accelerates, the demand for intelligent, high-performance power devices within charging stations and management systems is surging. The MMBF170L meets this need, delivering dependable power management and precise control for fast, efficient charging. Beyond drivetrain and charging systems, its advantages extend to auxiliary applications such as climate control, infotainment systems, and vehicle security — enhancing overall vehicle functionality.
