The recommended operating temperature range for the FM4003-W is -40°C to 125°C.
To ensure reliability, it's recommended to derate the power dissipation of the FM4003-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 FM4003-W is 400V, as specified in the datasheet.
To protect the FM4003-W from EOS, it's recommended to use a voltage regulator or a transient voltage suppressor (TVS) to limit the voltage and current, and to ensure proper PCB layout and design to minimize electromagnetic interference (EMI).
Yes, the FM4003-W is suitable for high-frequency switching applications up to 1 MHz, but it's recommended to consult the datasheet and application notes for specific guidance on layout, design, and component selection.
