VDS=-30V: Suitable for 5V/12V/24V systems, providing ample margin for negative voltage spikes to reduce avalanche breakdown risk.
VGS=±20V: Compatible with a wide range of logic levels, supporting direct connection to controllers/PMICs to simplify drive circuit design.
Vth=-3V: Moderate threshold voltage effectively suppresses false turn-on while ensuring fast and reliable turn-off under PWM drive.
RDS(on)=4mΩ @ VGS=10V, 6mΩ @ VGS=4.5V: Extremely low on-resistance, greatly reducing full-load conduction losses, significantly reducing required copper area for heat dissipation and system temperature rise.
ID=-120A: Extremely ample continuous current capability to handle surge and peak demands of high-power loads.
Package DFN8(5X6): Low parasitic inductance, excellent thermal resistance characteristics, supporting high-density assembly for module miniaturization and efficient heat dissipation.
Domain and module applications：
High-power battery protection module: Ultra-low internal resistance reduces self-heating of the protection board, and fast turn-off characteristics ensure microsecond-level response during overcurrent/short circuit.
DC-DC converter and synchronous rectification: Replaces traditional devices in P-MOS negative voltage topology, significantly improving heavy-load efficiency, suitable for high-power density power modules.
Low-voltage motor drive: Low PWM switching loss, smoother motor operation, and significantly reduced controller temperature rise.
Power tools and vehicle load switches: -120A ultra-high current margin and DFN8 strong heat dissipation capability meet high-intensity impact load requirements.
Portable device power management: Low conduction voltage drop improves charging and discharging efficiency, small package aids ultra-thin and compact design.
LED lighting drive: Low conduction loss reduces constant current source power waste, supports multi-channel parallel connection, improving overall lamp efficiency and reliability.
Industrial control modules: Wide safe operating area and high-performance Trench process, suitable for 24V industrial bus and harsh electromagnetic environments. Selection Summary: FDMS6673BZ-NC-VB achieves an excellent balance between extremely low on-resistance, ultra-high current capability, and compact packaging. It is a high-performance general-purpose choice for 30V low-voltage high-power negative voltage switch applications, especially suitable for projects with strict requirements on heat dissipation, efficiency, and reliability.
