IPB120N10S405ATMA1-VB Product details
Back to previous pageProduct introduction：
The IPB120N10S405ATMA1-VB is a Single N-MOSFET optimized for medium-voltage, high-current power switching applications. Using Trench technology, it combines extremely low conduction losses with excellent switching characteristics. The TO263 (DPAK) package achieves a good balance between heat dissipation and assembly process compatibility. The combination of 100V withstand voltage, 140A continuous current capability, and 4mΩ ultra-low on-resistance makes it a cost-effective power switch option for applications such as servo motors, lithium battery protection, DC-DC converters, and automotive power modules, particularly suitable for systems with strict requirements on heat control and high current margin.

VDS=100V: Suitable for 24V/48V/60V and some 72V systems, providing ample margin for inductive load turn-off spikes and bus transient overvoltages, reducing the risk of avalanche breakdown.
VGS=±20V: Compatible with standard gate drive circuits and 10V~15V drive voltages, can be directly driven by dedicated driver ICs or operational amplifiers without complex level shifting.
Vth=3V (typical): Moderate threshold voltage for strong noise immunity, while ensuring deep linear region operation under sufficient gate drive, suitable for industrial PWM control.
RDS(on)=4mΩ @ VGS=10V: Ultra-low on-resistance minimizes conduction losses, significantly reducing temperature rise under high current conditions, potentially allowing for smaller heatsinks or fanless designs.
ID=140A: Ample continuous current rating to handle heavy loads, stall conditions, and short-term surge currents, ensuring system reliability.
Package TO263: Compatible with standard SMD reflow soldering, the large bottom heatsink enhances thermal conduction efficiency, balancing PCB layout flexibility with long-term reliability.
