PHD78NQ03LT,118-VB Product details
Back to previous pageProduct introduction：
Imagine this: You are designing a high-power brushless motor driver, and the PCB needs to withstand surge currents of nearly a hundred amps, while also controlling heat and loss. Ordinary MOS tubes either have too high on-resistance or insufficient heat dissipation in the package. VBsemi PHD78NQ03LT,118-VB is designed for this—it integrates 20V withstand voltage, 100A ultra-high current carrying capacity, and an on-resistance as low as 4.5mΩ into a standard TO252 power package, making high-current, low-voltage switching applications efficient and effortless.

- Voltage 20V, suitable for low-voltage high-current applications, reducing switching stress
- Gate drive range ±20V, compatible with various drive voltages for flexible control
- Threshold voltage 0.5~1.5V, can be directly driven by low-voltage logic, simplifying design
- On-resistance 6mΩ (2.5V drive) / 4.5mΩ (4.5V drive), extremely low loss, less heat generation
- Maximum current 100A, TO252 package can handle high current
- Trench technology, fast switching speed, excellent figure of merit
Domain and module applications：
- Brushless Motor Drivers – Acts as a power switch, withstanding high transient currents, reducing conduction losses, and improving drive efficiency.
- Power Tools / Garden Machinery – Maintains low temperature rise under high-current stall or startup conditions, reliable and durable.
- Battery Protection Boards / Lithium Battery Packs – Quickly disconnects during overcurrent or short circuits, protecting battery cells, supporting high-rate discharge.
- DC-DC Step-Down Modules – Replaces Schottky diodes in synchronous rectification topologies, significantly improving conversion efficiency.
- Low-Voltage High-Current Power Switches – Used for power path management in servers and communication equipment, achieving low-heat switching.
- Automotive Electronics / Vehicle Low-Voltage Loads – Withstands 12V/24V system voltage fluctuations, stably driving windows, fans, heaters, etc. One Sentence Summary: PHD78NQ03LT,118-VB is not an ordinary MOS tube; it is the 'power heart' and 'low-loss weapon' in your low-voltage high-current design.
