Key Features and Innovations

STMicroelectronics’ STL300N4F8 (industrial-grade) and STL305N4F8AG (automotive-grade) MOSFETs bring a range of benefits for modern power electronics:

1. Standard Threshold Voltage (VGS(th)):
   • Ensures compatibility with non-logic-level control for broad design flexibility.
2. High Power Efficiency:
   • Maximum RDS(on) of just 1mΩ ensures minimal conduction losses.
   • Total gate charge of 65nC (typical) and low capacitances (Ciss, Crss) enhance dynamic performance and reduce switching losses.
3. Robust Body Diode:
   • Low forward voltage and fast reverse recovery support efficiency and reliability in high-frequency switching environments.
4. Thermal Ruggedness:
   • A maximum operating junction temperature of 175°C enables usage in extreme environments.
   • Reduced heat dissipation simplifies thermal management, saving space and cutting costs.
5. Compact and Cost-Effective:
   • A compact PowerFLAT 5×6 package, including wettable flanks for automotive applications, provides a space-efficient footprint and competitive pricing.
