The maximum operating temperature range for the IR2085STRPBF is -40°C to 150°C.
To ensure proper cooling, a heat sink with a thermal resistance of less than 10°C/W is recommended. Additionally, ensure good airflow around the device and avoid blocking the heat sink fins.
A 2-layer or 4-layer PCB is recommended, with a solid ground plane and a separate power plane for the high-voltage supply. Keep the high-frequency components (e.g., bootstrap capacitor, gate resistor) close to the IC.
Choose a capacitor with a voltage rating of at least 25V, a capacitance value between 10nF to 100nF, and a low ESR (Equivalent Series Resistance). A ceramic or film capacitor is recommended.
A gate resistor value between 10Ω to 100Ω is recommended, depending on the specific application and switching frequency. A lower value can reduce switching losses, but may increase EMI.
