RQ3P270BLFRATCB-VB is a Single N-MOS optimized for medium-voltage power switching scenarios, using Trench technology to balance low conduction losses and efficient switching characteristics. The DFN8(3X3) package achieves a good balance between thermal performance and board space, suitable for high-density power designs. The combination of 100V withstand voltage, 35.5A continuous current capability, and 17mΩ on-resistance makes it an ideal choice for replacing traditional DPAK packages in communication power supplies, industrial control, and automotive systems.
VDS=100V: Suitable for 24V/48V/60V systems, providing ample spike voltage margin, significantly reducing avalanche breakdown risk. VGS=±20V: Wide gate voltage range, compatible with 3.3V~12V logic levels, can directly connect to MCU/PWM controllers, simplifying drive circuits. Vth=1.8V (Typical): Low threshold voltage ensures reliable turn-on under low-voltage drive conditions, suitable for multi-cell battery voltage fluctuation scenarios. RDS(on)=17mΩ @ VGS=10V: Ultra-low on-resistance, minimal conduction loss at full load, effectively reducing PCB thermal design pressure. ID=35.5A: High current carrying capacity, meeting continuous and peak current demands of loads like motors and power supplies. Package: DFN8(3X3): Miniaturized package, low parasitic inductance, supports high-frequency switching, optimizes thermal resistance path, enhancing power density.
Domain and module applications：
DC-DC Converters: Replaces Schottky diodes in synchronous rectification applications, significantly improving efficiency at heavy loads and aiding module miniaturization. Motor Drive and Control: Low switching losses and low conduction voltage drop enable smoother PWM speed control, significantly reducing controller temperature rise. Battery Protection and Management: Fast turn-off capability ensures reliable protection during overcurrent/short circuit; low internal resistance reduces self-heating losses on the protection board. Communication Base Station Power Supplies: 100V voltage rating with high current capability adapts to hot-swap and surge conditions in -48V bus architectures. Automotive Auxiliary Power Supplies: Wide operating temperature range and high-reliability Trench technology suit 12V/24V automotive electrical systems. Industrial Automation Equipment: High current margin and low on-resistance meet the drive requirements of inductive loads such as solenoid valves and air pumps. LED Lighting Drivers: Low conduction voltage drop reduces constant current source losses; supports multi-channel parallel connection, improving overall system efficiency and light output. Selection Summary: The RQ3P270BLFRATCB-VB achieves an excellent balance between voltage rating, on-resistance, current capability, and package size, making it a cost-effective general-purpose choice for 100V medium-voltage switching applications, especially suitable for projects with strict requirements on heat dissipation, power density, and reliability.
