Product introduction：
TPH1R405PL,L1Q-VB is a Single N-MOSFET deeply optimized for low-voltage, high-power switching scenarios. The Trench technology achieves an excellent balance between ultra-low on-resistance and high switching speed. The DFN8(5X6) package combines high current heat dissipation capability with a compact footprint. The combination of 40V voltage tolerance, 100A continuous current, and 0.8mΩ on-resistance makes it an ideal choice for high-density power applications such as server power supplies, motor drives, and lithium battery protection, especially suitable for replacing traditional DPAK/TO-252 packages, enhancing power density while effectively reducing system temperature rise.

- VDS=40V: Suitable for 12V/24V/36V systems, providing ample voltage margin for load transients and parasitic spikes, enhancing avalanche reliability.
- VGS=±20V: Wide gate drive voltage tolerance, compatible with 4.5V/10V logic levels, flexible for use with MCUs, gate drivers, or PMICs.
- Vth=3V (Typical): Moderate threshold voltage, strong noise immunity, ensures deep linear region operation under 10V drive, fully reducing conduction losses.
- RDS(on)=0.8mΩ @ VGS=10V: Industry-leading ultra-low on-resistance, significantly reducing full-load conduction losses, effectively suppressing self-heating in high-current scenarios, and reducing heatsink size.
- ID=100A: Ample continuous drain current margin, meeting demanding load requirements for high-power density converters, high-power BLDC drives, and battery pack active balancing.
- Package DFN8(5X6): Bottom-side thermal pad design, low thermal resistance, low parasitic inductance, supports high-frequency switching, saves PCB area, and optimizes power loop layout.
Domain and module applications：
- Server/Telecom Power Supplies: Used in synchronous rectification and OR-ing circuits, ultra-low on-resistance significantly improves full-load efficiency, reducing data center cooling costs.
- High-Power Motor Drives: In scenarios like drones, power tools, and robot joints, 100A high-current capability and low switching losses match PWM high-frequency control, improving dynamic response and reducing driver temperature rise.
- Lithium Battery Protection and BMS: Low internal resistance in charge/discharge circuits reduces protection board heating; 40V voltage rating supports multi-cell lithium batteries, meeting high-current shutdown requirements during overcurrent/short circuit.
- Electric Vehicle Power Management: Suitable for 12V/24V/36V vehicle buses; DC-DC conversion, load switches, and battery switching circuits can all leverage its low-loss and high thermal reliability advantages.
- High-Power DC-DC Converters: As the main switch in buck/boost topologies, achieving peak efficiency above 98%, supporting further module miniaturization.
- Power Sockets and Industrial Control: Generous SOA and strong avalanche capability adapt to inductive load start/stop, enhancing long-term stability of industrial equipment in harsh electromagnetic environments.
**Selection Summary**: The TPH1R405PL,L1Q-VB achieves an excellent balance between extremely low on-resistance, high-current carrying capacity, and compact DFN8(5X6) packaging. It is a high-performance general-purpose choice for 40V low-voltage, high-power switching applications, especially suitable for projects with strict requirements on efficiency, temperature rise, and power density.
