Procurement Notes

Verify the specific datasheet revision (DS00004106A) matches your design requirements before procurement. Confirm that the isolation voltage rating of 2500 V RMS meets your system safety standards. Ensure proper electrostatic discharge handling procedures are followed during installation, as the devices are sensitive to static damage. Check mounting torque specifications for M4 screws to ensure reliable mechanical connection.

Selection Notes

Select this component when high blocking voltage and low leakage current are critical for system efficiency. The low junction-to-heatsink thermal resistance makes it suitable for applications requiring effective heat management without excessive cooling infrastructure. Consider the extended temperature range if the operating environment experiences significant thermal fluctuations or requires robust performance under varying load conditions.
