SMS3927-023LF

RF Diode Overview

The SMS3927-023LF is a surface mount Schottky quad mixer diode manufactured by Skyworks Solutions, Inc. It features a medium barrier junction and is housed in an SOT-143 package. The device provides four independent Schottky diodes configured as a crossover quad. Key electrical specifications include a reverse voltage rating of 2V, a capacitance range of 0.3 to 0.5 pF at 0V and 1MHz, and a forward voltage between 310 mV and 370 mV at 1 mA. Maximum power dissipation is rated at 75 mW, with an operating temperature range from -65°C to +150°C.

RF Diode Feature Summary

• Crossover quad configuration for double balanced mixer applications
• Tight parameter distribution ensuring uniformity across all four junctions
• Low capacitance design optimized for wireless frequencies into the C-band
• 100% DC tested for guaranteed performance consistency

RF Diode Applications

• Double balanced mixers
• Modulators
• Frequency multipliers
• High-volume commercial systems

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official datasheets. Ensure proper ESD handling protocols are followed during storage and assembly. Check for updated product change notifications regarding manufacturing sites or material composition changes before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a medium barrier Schottky diode is required for mixer circuits. Compare against low barrier variants like the SMS3926 series if lower forward voltage drop is critical. Verify that the SOT-143 package dimensions align with the target PCB layout. Ensure the 2V reverse voltage rating meets the peak inverse voltage requirements of the specific application circuit.

RF Diode Part Context

This part belongs to the Skyworks Surface Mount Schottky Quad Mixer Diodes family. It shares the same SOT-143 footprint and general testing standards as other members like the SMS3926 and SMS3940 series. The primary differentiator is the medium barrier junction type, which offers a balance between forward voltage and switching speed compared to low or high barrier alternatives within the same package.

RF Diode Replacement Considerations

The SMS3926-023LF serves as a functional substitute within the same package but utilizes a low barrier junction instead of medium. Designers must account for differences in forward voltage characteristics when swapping these parts. No other direct pin-compatible replacements are documented in the provided datasheet.
