Typical Applications
STL190N4F7AG is suitable for 6 applications: Automotive Engine Control Unit, DC-DC Converter, Motor Control, Battery Management System, Industrial Power Supply, LED Lighting.
Automotive Engine Control Unit
The STL190N4F7AG is ideal for automotive engine control units (ECUs) due to its AEC-Q101 qualification and high current capability. It is used in power distribution, solenoid drivers, and motor control circuits within the ECU. The low on-resistance (2.2 mOhm) minimizes power loss, while the 40V rating handles load dump transients. The PowerFLAT 5x6 package allows compact PCB designs, and the wide operating temperature range (-55Β°C to +175Β°C) ensures reliability under hood. In a typical ECU, the MOSFET switches inductive loads such as fuel injectors and relays, where its avalanche energy rating of 200 mJ protects against voltage spikes.
Recommended
DC-DC Converter
In DC-DC converters, the STL190N4F7AG serves as a synchronous rectifier or main switch. Its low gate charge (60 nC) enables high-frequency operation, reducing transformer size and improving power density. The low on-resistance minimizes conduction losses, achieving efficiencies above 95% in 12V to 5V conversions. The fast body diode reverse recovery (30 ns) reduces switching losses in synchronous rectification. For a 12V input, 5V output converter at 20A, the MOSFET dissipates only 0.88W at full load, allowing a compact heatsink. The PowerFLAT 5x6 package's low thermal resistance (1.2 C/W) ensures stable operation.
Recommended
Motor Control
The STL190N4F7AG is used in brushless DC (BLDC) motor drives for automotive and industrial applications. Its high current rating (190A) supports motors up to several kilowatts. The low on-resistance reduces heat generation, while the fast switching speed enables PWM control at frequencies up to 20 kHz. In a three-phase inverter, six MOSFETs are used to drive the motor phases. The avalanche ruggedness ensures reliability during motor stall conditions. The AEC-Q101 qualification makes it suitable for electric power steering and cooling fan motors.
Recommended
Battery Management System
In battery management systems (BMS), the STL190N4F7AG is used for cell balancing and protection circuits. Its low on-resistance minimizes power loss during balancing, and the 40V rating is suitable for 12V and 24V battery packs. The MOSFET can handle high currents during charge and discharge, and its avalanche rating protects against inductive spikes from wiring. The AEC-Q101 qualification ensures reliability in automotive battery systems. In a typical BMS, the MOSFET is placed in series with the battery to disconnect the load in case of overcurrent or overvoltage.
Recommended
Industrial Power Supply
The STL190N4F7AG is used in industrial power supplies for high-efficiency AC-DC and DC-DC conversion. Its low on-resistance and fast switching reduce losses, enabling compact designs with high power density. The device can handle high currents, making it suitable for server power supplies and welding equipment. The wide operating temperature range allows operation in harsh industrial environments. In a typical power supply, the MOSFET is used in the primary side switching stage, where its low gate charge reduces drive complexity.
Recommended
LED Lighting
The STL190N4F7AG is used in LED lighting drivers for automotive and industrial applications. Its high current capability supports high-power LED arrays, and the low on-resistance minimizes power loss, improving overall efficiency. The fast switching speed enables PWM dimming at high frequencies without flicker. The AEC-Q101 qualification makes it suitable for automotive headlamps and daytime running lights. In a typical LED driver, the MOSFET is used as a switch in a buck converter to regulate LED current.

Key Differentiators
- Automotive-grade AEC-Q101 qualification (vs STL190N4F7)
- Lower on-resistance than cross-brand alternatives (vs NVMFS5C410N)
- Higher avalanche energy rating (vs IPB190N04S4-02)
Design Notes
The PowerFLAT 5x6 package has a thermal resistance of 1.2 C/W (junction-to-ambient). At 190A and 2.2 mOhm, power dissipation is approximately 79W, which would require a heatsink or large copper area. For continuous operation, ensure the junction temperature stays below 175Β°C. Use thermal vias and a minimum of 1 square inch of copper on the drain pad.
Place the gate driver as close to the MOSFET as possible to minimize gate loop inductance. Use a 10-ohm gate resistor to dampen ringing. The source pins should be connected to a low-impedance ground plane to reduce common-source inductance. For high-current paths, use multiple vias and wide traces to handle the current.
Do not exceed the maximum gate-source voltage of Β±20V. Ensure the gate drive voltage is at least 10V to achieve the specified on-resistance. When switching inductive loads, the avalanche energy rating of 200 mJ must not be exceeded; use a snubber or clamp circuit if necessary. Also, be aware of the body diode's reverse recovery time (30 ns) in synchronous rectification applications.
