STP85NF55 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the STP85NF55?
  The maximum operating temperature range for the STP85NF55 is -40°C to 150°C.
• How do I ensure the STP85NF55 is properly biased for optimal performance?
  To ensure proper biasing, connect the gate to a voltage source through a resistor (e.g., 1 kΩ) and ensure the drain-source voltage is within the recommended range (typically 10-20 V).
• What is the recommended gate drive voltage for the STP85NF55?
  The recommended gate drive voltage for the STP85NF55 is between 10-15 V, with a maximum gate-source voltage of ±20 V.
• How do I protect the STP85NF55 from overvoltage and overcurrent?
  Use a voltage regulator or a zener diode to limit the voltage, and consider adding a current-sensing resistor and a fuse or a current limiter to prevent overcurrent.
• What is the maximum allowed power dissipation for the STP85NF55?
  The maximum allowed power dissipation for the STP85NF55 is 150 W, but this can be increased with proper heat sinking and thermal management.
