SMP1320-079LF

RF Diode Overview

The SMP1320-079LF is a single PIN diode from the Skyworks SMP1320 series, housed in an SC-79 surface-mount package. It features a maximum reverse voltage of 50 V and a power dissipation rating of 400 mW at 25 °C lead temperature. The device exhibits a typical capacitance of 0.23 pF at 30 V reverse bias and 1 MHz frequency, with a maximum of 0.30 pF. Series resistance is typically 0.75 Ω at 10 mA forward current and 100 MHz, with a maximum of 0.90 Ω under the same conditions. Operating temperature ranges from -65 °C to +150 °C.

RF Diode Feature Summary

• Designed for high-isolation, series-connected switches in battery-operated circuits due to low capacitance and resistance characteristics.
• Suitable for high-volume switch applications operating from 10 MHz to more than 10 GHz.
• Rated for Moisture Sensitivity Level 1 (MSL1) and compatible with lead-free soldering processes up to 260 °C.

RF Diode Applications

• High-isolation RF switches
• Battery-operated wireless circuits
• High-volume wireless infrastructure components

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the official Certificate of Conformance provided by Skyworks Solutions Inc. Ensure handling procedures adhere to industry-standard electrostatic discharge precautions during storage and assembly.

RF Diode Selection Notes

Select this component when a small footprint SC-79 package is required for single-diode configurations. Verify that the 50 V reverse voltage limit meets circuit requirements. Consider the specific series resistance values at intended forward currents for insertion loss calculations in switch designs.

RF Diode Part Context

This part belongs to the SMP1320 series of plastic packaged, surface mountable PIN diodes. Other members include SMP1320-075LF (SC-70), SMP1320-011LF (SOD-323), and SMP1320-040LF (SOD-882). All share similar electrical performance profiles but differ in physical package dimensions and parasitic inductance.

RF Diode Replacement Considerations

Direct replacements within the same series include SMP1320-075LF, SMP1320-011LF, and SMP1320-040LF. Substitution requires verification of package footprint compatibility and confirmation that the alternative package's parasitic inductance does not impact high-frequency performance.
