IPD04N03LBG-VB Product details
Back to previous pageProduct introduction：
IPD04N03LBG-VB is a Single N-MOSFET deeply optimized for low voltage, high current power switching applications. Trench technology balances extremely low conduction loss with high switching reliability, and the TO252 package achieves a good balance between heat dissipation capability and soldering process compatibility. The combination of 30V withstand voltage, 85A current carrying capacity, and 4mΩ on-resistance makes it an ideal choice for high power, high density applications such as server power supplies, power tools, and automotive low voltage power distribution, especially suitable for cost-reduction and efficiency-improvement solutions that replace multiple paralleled small-package devices.

VDS=30V: Suitable for 5V/12V/24V systems, providing ample peak voltage margin for inductive load switching, reducing avalanche breakdown risk.
VGS=±20V: Compatible with 4.5V~12V logic level drive, can be directly controlled by MCU/gate driver, simplifying peripheral circuitry.
Vth=1.83V (Typical): Moderate threshold voltage ensures reliable turn-on under low-voltage drive conditions while maintaining good noise immunity.
RDS(on)=4mΩ @ VGS=10V: Ultra-low on-resistance minimizes conduction losses at full load, significantly reducing temperature rise and heat sink size.
ID=85A: Ample continuous current capability to handle transient high-current surges such as motor startup and battery short circuits.
Package TO252: Low thermal resistance, strong overcurrent capability, compatible with standard SMT processes, balancing power density and mass production reliability.
Domain and module applications：
Low-Voltage High-Current DC-DC Converters: Replacing multiple low-voltage MOSFETs in synchronous rectification or buck topologies, significantly improving heavy-load efficiency and simplifying layout.
Power Tools and Garden Machinery: Extremely low PWM losses in motor drives; controllable temperature rise under continuous high-current output, extending tool lifespan.
Automotive Low-Voltage Power Distribution Units: Ample voltage margin in 12V/24V automotive bus environments; low internal resistance reduces heating in wiring and connectors.
Battery Pack Protection Boards: 85A continuous current supports high-rate discharge; fast overcurrent/short-circuit切断 capability enhances system safety.
Server and Communication Power Supplies: High-efficiency synchronous rectification reduces overall system energy consumption; TO252 package facilitates airflow design and thermal simulation.
Industrial Motor Controllers: Low on-resistance reduces inverter power consumption, suitable for automation equipment requiring long-term high-load operation.
LED Large Screens and Lighting Drives: Reduces power loss in low-voltage constant current/constant voltage conversion; supports high-current parallel modules, improving overall system stability. Selection Summary: The IPD04N03LBG-VB achieves an excellent balance between ultra-low on-resistance, high-current carrying capacity, and the heat dissipation advantages of the TO252 package. It is a cost-effective general-purpose choice for high-power density and low-cost mass production in 30V low-voltage switching applications, particularly suitable for system designs with stringent requirements on thermal dissipation, efficiency, and reliability.
