2SK3704-1EX-VB Product details
Back to previous pageProduct introduction：
2SK3704-1EX-VB is a Single N-MOS deeply optimized for low-voltage, high-power switching scenarios. The Trench process balances extremely low conduction loss with high switching reliability, while the TO220F fully isolated package achieves an ideal balance between heat dissipation capability and system safety. The combination of 60V withstand voltage, 70A current carrying capacity, and 10mΩ-level on-resistance makes it a preferred device for medium-to-high-power applications such as motor drives, power conversion, and automotive electronics, especially suitable for industrial-grade designs requiring high current margins and low temperature rise.

VDS=60V: Suitable for 12V/24V/36V/48V systems, providing ample margin for inductive load spikes and bus transients, significantly improving system robustness.
VGS=±20V: Wide gate voltage range, compatible with 4.5V~12V logic level drives, flexible for use with MCUs, drivers, or dedicated gate driver ICs.
Vth=2.5V (typical): Moderate threshold effectively suppresses false triggering from noise while ensuring controllable turn-on capability at low gate voltage.
RDS(on)=10mΩ @ VGS=10V / 12mΩ @ VGS=4.5V: Ultra-low on-resistance, extremely low full-load loss, can significantly reduce heatsink size or cooling requirements.
ID=70A: Strong continuous current capability, sufficient to cover peak demands of high-power motors, battery main circuits, and high-current DC-DC converters.
Package TO220F: Fully molded structure requires no additional insulating pad, easy to install, low thermal resistance, suitable for prolonged high-load operation.
Domain and module applications：
Low-voltage High-power Motor Drives: Ultra-low internal resistance reduces PWM output stage losses, suitable for high-frequency, high-current scenarios like power tools and robots.
Battery Protection and Main Circuit Switches: 70A current capability ensures reliable on/off switching for large-capacity battery packs during charging/discharging; low heat generation extends protection board lifespan.
High-power DC-DC Converters: Replaces high-current diodes in synchronous rectification, significantly improving heavy-load efficiency while reducing thermal management costs.
On-board Auxiliary Power Supplies and Bus Power Distribution: 60V voltage withstand covers transient surges in 12V/24V vehicle systems; TO220F package is suitable for reliable fixation on the wiring harness end.
UPS and Inverter Output Stage Switches: Low on-resistance reduces static power consumption; high robustness adapts to the continuous operation conditions of uninterruptible power supplies.
Industrial Power Supplies and Welding Equipment: High current margin handles start-up surges from inductive loads; excellent thermal performance ensures long-term full-load operation.
Power Distribution Modules: Suitable as a low-voltage, high-current on/off device, simplifying circuit design and improving system power density. Selection Summary: The 2SK3704-1EX-VB, with its robust parameters of 60V/70A/10mΩ and the easy-to-use TO220F package, achieves a high degree of unity between performance and reliability in the field of high-current, low-voltage switching. It is a cost-effective preferred solution for motor drives, power conversion systems, and vehicle electronics, especially suitable for projects with stringent requirements on current capability, conduction loss, and long-term heat dissipation.
