SMS7630-040LF

RF Diode Overview

The SMS7630-040LF is a single silicon Schottky diode from the Skyworks mixer and detector series, housed in an SOD-882 surface-mount package. It features a minimum breakdown voltage of 1 V at 100 μA and a typical capacitance of 0.3 pF at 0.15 V. The forward voltage ranges from 60 to 120 mV at 0.1 mA and 135 to 240 mV at 1 mA. With a maximum pair delta VF of 10 mV at 1 mA and a typical reverse resistance of 5000 Ω, it supports operation up to 24 GHz. Absolute maximum ratings include a steady-state forward current of 50 mA and power dissipation of 75 mW.

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and halogen-free status against current regulatory requirements. Ensure storage conditions maintain Moisture Sensitivity Level 1 integrity before solder assembly. Review datasheet specifications for absolute maximum ratings to prevent permanent damage during operation.

RF Diode Selection Notes

Select this component for low-barrier mixer and zero-bias detector implementations requiring minimal forward voltage drop. The SOD-882 package suits compact surface-mount layouts. Evaluate the 0.3 pF capacitance and 5000 Ω reverse resistance for high-frequency signal integrity. Consider the 1 V breakdown voltage when designing circuits operating near peak reverse limits.

RF Diode Part Context

This part belongs to the Skyworks SMS7630 series of surface-mountable plastic-packaged silicon mixer Schottky diodes. The series includes variants in SC-79, SOT-23, and SOD-882 packages. Wiring configurations encompass singles, series pairs, and reverse series pairs. These devices utilize advanced semiconductor technology combined with cost-effective packaging techniques for mass production.

RF Diode Replacement Considerations

SMS7621-040LF offers similar packaging but higher barrier voltage (2 V) and lower capacitance (0.25 pF). SMS7630-079LF provides the same electrical characteristics in an SC-79 package. SMS7630-005LF utilizes an SOT-23 package with identical series parameters.
