RF Diode Procurement Notes

Verify the manufacturer origin carefully, as the part number UM2101 is also associated with STMicroelectronics documentation for sensor development kits. Confirm that the specific component matches the Microchip Technology specification for a hermetically sealed axial PIN diode rather than a software utility or different semiconductor type.

RF Diode Selection Notes

Select this component when a hermetically sealed RF switch is required. Ensure the design accommodates the axial leaded package format. Verify that the 100V peak reverse voltage rating meets the circuit's maximum voltage requirements and that the low capacitance value is suitable for the intended frequency range.

RF Diode Part Context

This component belongs to the category of discrete semiconductor diodes, specifically PIN diodes used in radio frequency applications. It is distinct from microcontroller or sensor products sharing similar alphanumeric prefixes in other manufacturers' lineups.
