VDS=20V: Suitable for 5V/12V low-voltage systems, combined with low parasitic inductance design, meets fast transient response requirements.
VGS=±20V: Compatible with 1.8V~12V logic levels, can directly interface with MCU/PMIC or dedicated gate drivers, simplifying peripheral circuitry.
Vth=0.5~1.5V: Low threshold voltage ensures full conduction even under low-voltage drive conditions, ideal for battery-powered and low-voltage swing scenarios.
RDS(on)=4.5mΩ @ VGS=4.5V (Typical): Ultra-low on-resistance, extremely low conduction losses under full load, significantly reducing device temperature rise and heatsink size.
RDS(on)=6mΩ @ VGS=2.5V (Typical): Maintains very low on-resistance even under 2.5V low-voltage drive, supporting 3.3V and below logic drive.
ID=100A: Very high continuous current capability, capable of handling high-power pulse loads and sustained high current output, with ample margin.
Package TO252: Compatible with DPAK standard pads, excellent thermal performance, suitable for medium-to-high power PCB layouts, and easy for automated assembly.
Domain and module applications：
Low-Voltage High-Current DC-DC Converters: Used as synchronous rectifiers or load switches, ultra-low on-resistance significantly improves heavy-load efficiency and reduces power stage heat generation.
Battery Protection and Power Management: 100A high-current capability meets the needs of power battery protection boards; low internal resistance reduces self-consumption of the protection circuit, extending standby time.
Motor Drive Modules: Low PWM high-frequency switching losses, suitable for power tools, toy motors, and small drone ESCs, providing smoother temperature control.
Server/Communication Power Supplies: Achieves high-efficiency power conversion on the 12V bus; the TO252 package can withstand higher heat flux density.
Vehicle Low-Voltage Load Switches: 20V withstand voltage combined with a wide safe operating area adapts to inductive load turn-off spikes in 12V automotive systems, offering high reliability.
Lithium Battery Power Tools: High current density reduces the number of parallel devices, simplifying BMS design and assembly costs, and increasing overall power density. Summary: IRFR3711TRLPBF-VB offers extreme conduction performance and ample current margin in low-voltage, ultra-high-current applications. The 20V withstand voltage and ±20V gate drive range lower the design threshold, and the TO252 package balances heat dissipation and process compatibility, making it a high-performance, cost-effective choice for low-voltage, high-power switching applications.
