T405-600W Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the T405-600W is -40°C to 150°C, with a junction temperature (Tj) of up to 175°C.
  • To ensure proper cooling, use a heat sink with a thermal resistance of ≤ 1.5°C/W, and apply a thermal interface material (TIM) with a thermal conductivity of ≥ 5 W/mK. Also, ensure good airflow around the device.
  • Use a 4-layer PCB with a solid ground plane, and place the T405-600W near the edge of the board to minimize thermal resistance. Keep the input and output capacitors close to the device, and use wide traces for the power lines.
  • Use a voltage supervisor or overvoltage protection (OVP) circuit to prevent voltage exceeding 600V. Implement overcurrent protection (OCP) using a current sense resistor and a comparator or a dedicated OCP IC.
  • Use a ceramic or film capacitor with a value of 1-10 μF, and a voltage rating of at least 630V. The capacitor should be placed close to the device and have low equivalent series resistance (ESR).
