MPP4205-206

RF Diode Overview

The MPP4205-206 is a silicon PIN diode limiter manufactured by Microchip Technology, designed for non-hermetic MMSM applications. It operates within a temperature range of -55°C to +150°C and utilizes a 0402 (1005 metric) surface-mount package. Key electrical parameters include a maximum peak reverse voltage of 25V, a capacitance of 0.15pF at 10V and 1MHz, and a resistance of 2 ohms at 10mA and 100MHz.

RF Diode Feature Summary

• Utilizes silicon technology for robust RF limiting performance
• Features a compact 0402 surface-mount footprint for space-constrained designs
• Supports high operating temperatures up to 150°C

RF Diode Applications

• RF signal limiting circuits
• Microwave protection stages
• High-frequency switching applications

RF Diode Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering. Confirm that the non-hermetic construction aligns with the environmental conditions of the target assembly. Ensure compatibility with standard reflow soldering profiles for the 0402 package type.

RF Diode Selection Notes

Select this component when a low-capacitance PIN diode is required for frequencies around 100MHz. The 25V reverse voltage rating suits moderate power handling needs. Consider the 0402 package size for board real estate optimization compared to larger hermetic packages.

RF Diode Part Context

This part belongs to the MPP420x series of PIN diodes from Microchip Technology. The series includes variants such as MPP4201 through MPP4204, sharing similar structural characteristics but differing in specific electrical ratings or packaging options. These components are categorized under RF diodes and limiters.

RF Diode Replacement Considerations

Direct substitutes may include other parts from the MPP420x family if electrical parameters match. Verify pinout and package dimensions before swapping. Cross-referencing with general-purpose RF PIN diodes requires careful validation of capacitance and reverse voltage specs.
