As a core component in power management and switching circuits, MOSFETs directly determine the efficiency, reliability, and miniaturization of electronic systems. ROHM Semiconductor, a global leader in semiconductor technology, has built a comprehensive MOSFET portfolio centered on Super Junction technology and low-power design, covering high-voltage industrial, small-signal, and application-specific scenarios. Its flagship PrestoMOS™ series, in particular, breaks through the performance bottlenecks of traditional MOSFETs, delivering ultra-low on-resistance and high-speed switching for energy-saving applications. To ensure genuine procurement, stable inventory, and professional technical support, ROHM partners with top-tier authorized distributors worldwide, enabling seamless access to these high-performance components for manufacturers and designers.
Core Product Lines & Technical Advantages
ROHM’s MOSFETs are tailored to diverse application needs, with three key product lines leading the market in performance and versatility:
1. Super Junction MOSFETs (PrestoMOS™ Series)
Optimized for high-voltage (600V-800V) power applications, these MOSFETs adopt ROHM’s proprietary Super Junction technology to achieve a balance of low loss and high-speed switching, addressing the core pain points of motor drives and power supplies:
Low-Noise Series (R60xxRNX): Ideal for small motor drives in refrigerators, ventilation fans, and other white goods. It reduces noise suppression man-hours and external components, with 600V breakdown voltage, typ. Rds(on) as low as 0.08Ω (Vgs=10V), and compact SMD packages for space-constrained designs .
High-Speed Diode-Built-in Series (R60xxVNX): Features the industry’s fastest reverse recovery time, making it suitable for high-power applications such as EV chargers, server power supplies, and air conditioner inverters. The built-in high-speed diode (patented by ROHM) enhances energy efficiency in motor and inverter circuits .
Low On-Resistance Series (R60xxYNX): A 4th-generation Super Junction MOSFET with industry-leading low Rds(on) and high-speed switching, designed for industrial power supplies and solar energy systems, contributing to maximum power conversion efficiency .
Notably, ROHM’s compact SOT-223-3 package for 600V Super Junction MOSFETs reduces area by 31% and thickness by 27% compared to conventional TO-252 packages, enabling smaller, lower-profile designs while maintaining compatibility with existing land patterns .
2. Small-Signal MOSFETs
Engineered for low-current, compact applications, these MOSFETs emphasize low-voltage drive and miniaturization:
RUR020N02: A 1.5V drive N-channel MOSFET with ultra-low Rds(on) (0.17Ω typ. at Vgs=1.5V) and compact TSMT3 package (2.8×2.9mm). Ideal for mobile devices and low-power IoT modules, with RoHS compliance and an 8-year product longevity program .
Note on QS8M31: This 60V Nch+Pch dual MOSFET is not recommended for new designs or design diversion, though it remains RoHS compliant with a TSMT8 package .
3. Application-Specific MOSFETs
AI Server MOSFETs (RY7P250BM): A 100V power MOSFET with wide SOA (Safe Operating Area) and low on-resistance, tailored for hot-swap circuits in AI servers, ensuring stable operation during load changes .
800V Industrial MOSFETs (R80xxKNX): Designed for LED lighting and industrial power supplies, offering high breakdown voltage and reliable performance in harsh industrial environments .
