Procurement Notes

Verify the specific ordering suffix and revision level against the official Microchip datasheet before procurement. Confirm RoHS compliance status and environmental declarations directly from the manufacturer's documentation. Check for any Product Change Notifications (PCN) or errata sheets that may impact mechanical dimensions or electrical characteristics. Ensure the supplier provides traceability documentation consistent with Microchip's quality standards.

Selection Notes

Select this component for designs requiring high voltage handling and significant RF power output at 40 MHz. Evaluate thermal management requirements carefully due to the 750 W power dissipation rating. Compare the 1.2 kV breakdown voltage against circuit peak voltages to ensure adequate safety margins. Consider the T1 package mounting style when designing the PCB or heatsink interface.
