RF Diode Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm packaging type, as variants exist with different reel or tape specifications. Confirm RoHS3 compliance status through the latest datasheet revision. Check for Product Change Notifications regarding manufacturing site or label changes before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a low-capacitance PIN diode is required for high-frequency RF paths. Ensure the 25V reverse voltage rating exceeds the maximum expected signal swing. Verify that the 0402 package size aligns with the PCB layout constraints and that the operating temperature range meets the system's environmental requirements.

RF Diode Part Context

The MPP4204-206 belongs to the MPP4201-MPP4205 family of silicon PIN diodes from Microchip Technology. These devices are commonly used in microwave and RF systems where fast switching and low insertion loss are critical. The MPP4204 variant specifically offers balanced performance characteristics for general-purpose RF limiting and switching tasks.

RF Diode Replacement Considerations

Direct substitutes within the same series include MPP4201-206, MPP4202-206, MPP4203-206, and MPP4205-206. Cross-compatibility depends on specific electrical parameter matching, such as breakdown voltage and capacitance. Verify pinout and package dimensions remain identical before substitution.
