3N0404 Power MOSFET Transistor Chip – High-Current Switching Device for Automotive ECU Applications

3N0404 is a high-performance power MOSFET transistor chip designed for automotive electronic control units (ECUs).

It functions as a fast-switching semiconductor device capable of handling moderate to high current loads.
Typical applications include driving injectors, ignition coils, fuel pumps, cooling fans, and solenoid valves in engine management systems.

The chip features a very low on-resistance (RDS(on)), which minimizes power dissipation and heat generation during conduction.
Fast switching characteristics allow precise timing control required for fuel injection and ignition timing.

Maximum drain current rating supports continuous operation up to several amperes, with peak currents handling brief overloads.
Drain-to-source voltage rating accommodates typical automotive electrical system voltages including load dump transients.

Built-in ESD protection diodes guard against static discharge damage during handling and operation.
The device is designed to operate reliably in the harsh under-hood environment with wide temperature extremes.

Gate drive voltage levels are compatible with standard 3.3V and 5V microcontroller outputs used in modern ECUs.
No additional gate driver circuitry is required for most switching applications, simplifying PCB design.

The 3N0404 comes in a compact surface-mount package suitable for space-constrained engine control boards.
It is an ideal replacement part for failed power transistors in aftermarket ECU repairs and module rebuilding.

Operating temperature range spans -40°C to +125°C, ensuring dependable performance in extreme automotive conditions.
