FDU8580-VB Product details
Back to previous pageProduct introduction：
The FDU8580-VB is a Single N-MOSFET deeply optimized for low-voltage high-power switching scenarios. The Trench technology balances extremely low switching losses with high reliability, and the TO251 package achieves a good balance between heat dissipation capability and ease of installation. The combination of 30V withstand voltage, 50A current carrying capability, and 7mΩ on-resistance makes it an ideal cost-effective and efficiency-improving alternative to traditional DPAK or D2PAK packaged devices, especially suitable for medium-to-high power, high-density assembly applications.

VDS=30V: Suitable for 5V/12V/24V systems, providing sufficient margin for voltage spikes, reducing the risk of avalanche breakdown.
VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly connected to MCU/PMIC, eliminating the need for level shift circuits.
Vth=1.7V (typical): Can still enter the fully enhanced region under low-voltage drive, especially suitable for battery voltage decay scenarios.
RDS(on)=7mΩ @ VGS=10V, 9mΩ @ VGS=4.5V: Ultra-low on-resistance significantly reduces full-load temperature rise, allowing for smaller heatsink or copper area.
ID=50A: Ample continuous current margin to handle peak demands of high-current loads like motors and power supplies.
Package TO251: Through-hole package with low thermal resistance and reliable soldering, suitable for industrial mass production and high-power-density layouts.
Domain and module applications：
Low-Voltage High-Current DC-DC Converters: Replaces Schottky in synchronous rectification, significantly improving heavy-load efficiency, facilitating module miniaturization.
Battery Protection and BMS: Ultra-low internal resistance reduces self-heating of the protection board, and high current capability meets the overcurrent protection needs of power battery packs.
Low-Voltage Motor Drives: Low PWM switching losses result in smoother motor operation and significantly lower controller temperature rise.
Power Tools and Portable Device Power Supplies: 50A current carrying capability covers high-power scenarios, Trench technology ensures high efficiency and stability.
Automotive Auxiliary Power Supplies: Voltage margin and wide operating temperature range adapt to 12V/24V vehicle buses, offering high reliability.
LED Lighting Drivers: Low conduction voltage drop reduces constant current source power consumption, supports multi-channel parallel connection, improving overall luminaire efficacy.
UPS and Inverters: Low-side switching transistors can withstand high current surges, low internal resistance reduces system losses, improving overall unit efficiency.
Selection Summary: The FDU8580-VB achieves a balance between performance margin, package form factor, and system cost. It is a high cost-performance general-purpose choice for 30V low-voltage high-current switching applications, particularly suitable for projects with strict requirements on current carrying capacity, thermal dissipation, and reliability.
