CDC7631-000

RF Diode Overview

The CDC7631-000 is a bare die zero-bias silicon Schottky barrier detector diode designed for applications through the K band. It operates efficiently at tangential signal power levels without requiring external bias, minimizing noise. The device features a video impedance range of 5000 to 15000 Ω and a maximum Tangential Signal Sensitivity (TSS) of -56 dBm. Absolute maximum ratings include a reverse voltage of 2 V, forward current of 100 mA, and RF input power of 75 mW at 25 °C. Operating temperature ranges from -55 °C to +150 °C.

RF Diode Feature Summary

• High sensitivity suitable for low-power detection
• Low video impedance enabling wide video bandwidth
• Zero-bias operation minimizes noise
• Beam-lead design facilitates MIC integration

RF Diode Applications

• Video detectors
• Power monitors

RF Diode Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the beam-lead configuration. Ensure handling procedures follow industry-standard ESD precautions due to electrostatic discharge sensitivity. Validate that the specific lot meets environmental compliance requirements.

RF Diode Selection Notes

Select this model when a higher video impedance range between 5000 and 15000 Ω is required compared to lower impedance alternatives. The -56 dBm TSS rating indicates suitability for detecting very low signal levels. Ensure the application circuit can accommodate the beam-lead mounting style and provides appropriate RF matching structures for optimal sensitivity.

RF Diode Part Context

This component belongs to the CDC and DDC series of zero-bias Schottky detector diodes manufactured by Skyworks Solutions. These devices are specifically engineered for microwave integrated circuit applications where chip and wire bonding approaches are preferred over traditional packaged components.

RF Diode Replacement Considerations

The CDC7630-000 serves as a functional substitute within the same series. It shares identical electrical characteristics except for a lower video impedance range of 2000 to 6500 Ω and a slightly different TSS rating of -52 dBm.
