SMS3924-075LF

RF Diode Overview

The SMS3924-075LF is a surface-mount general-purpose Schottky diode from the Skyworks SMS392x series, rated for 70 V reverse voltage. It utilizes an SC-70 package with a parasitic inductance of 1.4 nH and operates at frequencies up to 6 GHz. Electrical specifications include a maximum reverse current of 200 nA at 50 V, a forward voltage range of 490 mV to 550 mV at 1 mA, and a total capacitance between 1.43 pF and 1.83 pF at 0 V. The device supports a maximum forward current of 50 mA and power dissipation of 75 mW at 25 °C lead temperature.

RF Diode Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm package type and compliance status. Confirm availability through authorized distributors as standard supply channels may vary. Ensure ESD precautions are strictly followed during handling and assembly to prevent damage to the semiconductor junction.

RF Diode Selection Notes

Select this component when a 70 V reverse voltage rating is required for RF applications operating up to 6 GHz. The SC-70 package provides a compact footprint suitable for space-constrained designs. Verify that the 75 mW power dissipation limit aligns with the thermal management capabilities of the target circuit board layout.

RF Diode Part Context

This part belongs to the SMS392x series, which includes variants rated at 8 V (SMS3922) and 20 V (SMS3923). All series members share similar low-cost plastic packaging and general-purpose Schottky characteristics designed for high-volume commercial use.

RF Diode Replacement Considerations

Direct substitutes within the same series include SMS3924-015LF and SMS3924-040LF, which share the 70 V rating but differ in package configuration.
