SMS3923-079LF

RF Diode Overview

The SMS3923-079LF is a surface-mount general-purpose Schottky diode from the Skyworks SMS392x series, rated at 20 V reverse voltage. It utilizes an SC-79 package with an inductance of 0.7 nH and operates within a temperature range of -65 °C to +150 °C. Key electrical specifications include a maximum reverse current of 500 nA at 15 V, a capacitance range of 0.83 pF to 1.30 pF at 0 V, and a forward voltage range of 310 mV to 370 mV at 1 mA. The device supports a maximum forward current of 50 mA and power dissipation of 75 mW at 25 °C lead temperature.

RF Diode Feature Summary

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent damage during assembly processes.

RF Diode Selection Notes

Select this component when a 20 V rated Schottky diode is required for RF applications up to 6 GHz. Compare against the SMS3922 (8 V) and SMS3924 (70 V) variants based on circuit voltage requirements. Verify that the SC-79 package dimensions fit the target PCB layout constraints.

RF Diode Part Context

This part belongs to the SMS392x series, which includes the SMS3922, SMS3923, and SMS3924 models. These are low-cost plastic packaged Schottky diodes designed for general-purpose use. The series offers tight parameter distributions and is available in single and dual series pair configurations.

RF Diode Replacement Considerations

Direct substitutes within the same family include the SMS3922-079LF and SMS3924-079LF. Selection depends on whether the application requires lower (8 V) or higher (70 V) reverse voltage ratings while maintaining the same SC-79 package and form factor.
