BUK98150-55A,135-VB Product details
Back to previous pageProduct introduction：
BUK98150-55A,135-VB is a Single N-MOS deeply optimized for low-voltage power switching and load management scenarios. The Trench technology balances low switching loss with high reliability, and the SOT223 package achieves a good balance between heat dissipation capability and board area. The combination of 60V withstand voltage, 4.5A current carrying capacity, and 76mΩ on-resistance makes it an ideal cost-reduction incremental option for replacing traditional DPAK or SOP-8 packaged devices, especially suitable for high-density, medium and low power applications.

VDS=60V: Adaptable to 12V/24V/36V systems, providing sufficient voltage spike margin, reducing avalanche breakdown risk, suitable for inductive load switching scenarios.
VGS=±20V: Compatible with 3.3V~12V logic levels, can be directly connected to MCU/PMIC, simplifying gate drive circuit design.
Vth=1.7V (Typical): Can be effectively turned on under low voltage drive, suitable for battery-powered and logic level direct drive applications.
RDS(on)=76mΩ @ VGS=10V, 85mΩ @ VGS=4.5V: Low on-resistance effectively reduces conduction losses, lowers full-load temperature rise, and can reduce heat sink copper area.
ID=4.5A: Continuous current capability meets the needs of most portable devices, home appliance control, and vehicle auxiliary loads; peak current capability is better than the conventional level for this package.
Package SOT223: Small size, low thermal resistance, suitable for medium power PCB layout, compatible with mainstream SMT processes, reducing manufacturing costs.
Domain and module applications：
Power Management Module: Low on-resistance improves DC-DC conversion efficiency, especially suitable for synchronous rectification and load switches.
Battery Protection Circuit: 60V withstand voltage provides higher safety margin, microsecond switching response ensures fast shutdown during overcurrent/short circuit, reducing self-heating.
Low Voltage Motor Drive: Low PWM switching losses, smoother motor operation, controllable controller temperature rise, suitable for medium and low power drives like fans and pumps.
Consumer Electronics Control: Logic level direct drive simplifies peripheral design, suitable for mass-produced products like smart sockets, electronic locks, USB power switching.
LED Lighting Drive: Low conduction voltage drop reduces constant current control power consumption, supports multiple parallel connections, improving overall lamp efficiency and reliability.
