BUK9Y07-30B,115-VB Product details
Back to previous pageProduct introduction：
BUK9Y07-30B,115-VB is a Single N-MOSFET deeply optimized for low-voltage, high-current power switching applications. Trench technology achieves an excellent balance between low on-resistance and fast switching capability, while the LFPAK56 package balances thermal performance with a compact footprint. The combination of 30V voltage rating, 90A continuous current capability, and 2.8mΩ ultra-low on-resistance makes it a preferred device for high-current applications such as communication power supplies, power tools, and automotive electronics, particularly suitable for replacing traditional DPAK or D2PAK packages to improve power density.

VDS=30V: Suitable for 5V/12V/24V systems, providing ample headroom for voltage spikes and reducing avalanche breakdown risk.
VGS=±20V: Compatible with a wide range of gate drive voltages, can be directly connected to MCU/PMIC or dedicated driver ICs, simplifying peripheral design.
Vth=0.8V (Typical): Low threshold voltage ensures full conduction even under low-voltage drive conditions, ideal for battery-powered and low-voltage rail applications.
RDS(on)=2.8mΩ @ VGS=10V, 3.36mΩ @ VGS=4.5V: Ultra-low on-resistance significantly reduces conduction losses, greatly lowers full-load temperature rise, reduces required copper area for heat dissipation, and improves system efficiency.
ID=90A: High continuous current capability, easily handles steady-state and transient peak demands of high-power loads.
Package LFPAK56: Low parasitic inductance, excellent thermal path, supports high-frequency switching operation, saves PCB area, and improves reliability.
