The recommended operating temperature range for the FM4004W-W is -40°C to 150°C.
To ensure reliability, it's recommended to derate the power dissipation of the FM4004W-W according to the temperature derating curve provided in the datasheet, and to ensure good thermal design and heat sinking.
The maximum allowable voltage for the FM4004W-W is 400V, as specified in the datasheet.
To protect the FM4004W-W from EOS, it's recommended to use a voltage regulator or a transient voltage suppressor (TVS) to limit the voltage and current surges, and to ensure proper PCB layout and design to minimize electromagnetic interference (EMI).
The typical junction-to-case thermal resistance of the FM4004W-W is 1.5°C/W, as specified in the datasheet.
