RF Diode Procurement Notes

Verify the specific ordering suffix and package configuration directly with Microchip Technology before procurement. Confirm that the non-hermetic chip style aligns with your assembly requirements. Ensure compatibility with your manufacturing process regarding lead termination. Request official documentation to validate current production status and any potential obsolescence notices prior to finalizing supply agreements.

RF Diode Selection Notes

Select this component when a high-speed silicon limiter is required for frequencies approaching 18 GHz. Consider the non-hermetic package constraint if environmental sealing is not provided by the system enclosure. Evaluate the 150 fF capacitance limit against your circuit impedance matching needs. Verify that the 10 mA forward current rating meets the biasing requirements of your application design.

RF Diode Part Context

This part belongs to the GC4701 series of PIN diodes manufactured by Microchip Technology. The series includes various configurations such as hermetic stud mounts and different plastic packages. The GC4701-01 specifically denotes the non-hermetic chip variant with leads, distinguishing it from surface mount or stud-mounted alternatives in the same product family.

RF Diode Replacement Considerations

Consult Microchip Technology for direct cross-reference recommendations. Verify electrical parameters such as capacitance and carrier lifetime against alternative parts. Ensure mechanical compatibility with existing PCB layouts or mounting structures.
