SMS3928-023LF

RF Diode Overview

The SMS3928-023LF is a surface mount Schottky quad mixer diode manufactured by Skyworks Solutions Inc. It features four independent junctions in an SOT-143 package, designed for high-volume commercial systems and double balanced mixers. The device utilizes low barrier junction technology with a rated reverse voltage of 2V and a maximum forward current of 50 mA per junction. Electrical specifications include a capacitance range of 0.3 to 0.5 pF at 0V and 1 MHz, and a maximum slope resistance of 8 ohms at 10 mA. The component operates within a temperature range of -65°C to +150°C and is lead-free compliant.

RF Diode Feature Summary

• Monolithic chip technology ensures uniformity of electrical characteristics across all four junctions.
• Tight parameter distribution minimizes performance variability in circuit applications.
• Low capacitance design is optimized for wireless frequencies extending into the C-band.

RF Diode Applications

• Double balanced mixers
• Modulators and frequency multipliers
• High-volume commercial RF systems

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Confirm that the requested part number matches the exact barrier type and packaging format required for the design. Ensure compliance with RoHS standards and check for any recent product change notices or end-of-life announcements from Skyworks Solutions Inc. to avoid supply chain disruptions.

RF Diode Selection Notes

Select this component when a compact quad configuration is required for mixer circuits operating up to the C-band. The SOT-143 package provides a small footprint suitable for space-constrained designs. Verify that the 2V reverse voltage rating and 75 mW power dissipation limits align with the system's peak signal levels and thermal management capabilities.

RF Diode Part Context

This component belongs to the Skyworks Surface Mount Schottky Quad Mixer Diodes series. It shares the same SOT-143 package form factor as related models like the SMS3926-023LF and SMS3927-023LF. The series includes variations with low, medium, and high barrier junctions to suit different mixer requirements while maintaining consistent physical dimensions.

RF Diode Replacement Considerations

Direct substitutes within the same family include the SMS3926-023LF and SMS3927-023LF. These alternatives share the identical SOT-143 package but differ in barrier voltage characteristics. Verify that the specific junction parameters of the replacement part meet the original circuit design requirements.
