BUK9Y113-100E,115-VB Product details
Back to previous pageProduct introduction：
BUK9Y113-100E,115-VB is a Single N-MOS optimized for medium and high voltage power switching scenarios. The Trench process balances low switching losses with high reliability, and the LFPAK56 package achieves an excellent trade-off between heat dissipation and board space. With a 100V withstand voltage, 69A current carrying capacity, and 11.6mΩ on-resistance, it is an ideal high-density option for replacing traditional DPAK or D2PAK package devices, especially suitable for high-current, high-efficiency, and space-constrained applications.

VDS=100V: Suitable for 24V/48V/60V systems, providing ample margin for voltage spikes, significantly enhancing avalanche breakdown ruggedness.
VGS=±20V: Compatible with 4.5V~12V logic levels, can directly connect to drivers, MCUs, or PMICs, simplifying gate drive circuit design.
Vth=1.4V (typical): Low threshold voltage ensures full conduction even under low-voltage drive conditions, ideal for battery-powered and voltage droop scenarios.
RDS(on)=11.6mΩ @ VGS=10V: Ultra-low on-resistance greatly reduces full-load conduction loss, allowing for smaller heatsink sizes.
RDS(on)=13.92mΩ @ VGS=4.5V: Maintains low impedance under low-voltage drive, improving system light-load and standby efficiency.
ID=69A: Ample continuous current margin, capable of handling high-current surge demands like motor startup and power supply hot-swap.
Package LFPAK56: Low parasitic inductance and thermal resistance, supports high-frequency switching, saves PCB area, and increases power density.
Domain and module applications：
DC-DC Converters: Replacing Schottky diodes in synchronous rectification can improve heavy-load efficiency by 2~3%, facilitating module miniaturization and high power density design.
Battery Protection Modules: 100V voltage withstand combined with low internal resistance ensures fast shutdown during overcurrent/short circuit and reduces self-heating of the protection board.
Motor Drives: High current capability and low switching losses make PWM control smoother, significantly reducing controller temperature rise, suitable for loads like power tools and fans.
Communication and Server Power Supplies: Wide voltage margin and low conduction loss meet 48V bus architecture requirements, improving overall conversion efficiency.
Automotive Auxiliary Power Supplies: Voltage withstand margin and wide operating temperature range suit 12V/24V automotive systems, reliably handling transient conditions like load dump.
LED Lighting Drivers: Low on-state voltage drop reduces constant current source power loss, supports multi-channel parallel connection, improving overall lamp efficiency and light output stability.
Electric Bicycle/Low-Speed EV Controllers: 69A current capability covers high-power output requirements; LFPAK56 package facilitates compact controller layout. Selection Summary: The BUK9Y113-100E,115-VB achieves an excellent balance between voltage withstand, on-resistance, current capability, and package size. It is a cost-effective general-purpose choice for 100V power switch applications, especially suitable for projects with strict requirements on efficiency, heat dissipation, and space.
