Its resistance is specified as 60 Ohm at a forward current of 1.5mA under 100MHz conditions. The component is housed in a SOD80 Minimelf surface-mount package.

RF Diode Feature Summary

• Engineered for radio frequency signal processing tasks
• Utilizes a compact surface-mount Minimelf package design

RF Diode Applications

• RF switching circuits
• Attenuator networks
• Phase shifters

RF Diode Procurement Notes

Verify the specific manufacturer part number against official Vishay documentation to ensure authenticity. Confirm that the received components match the SOD80 Minimelf package specifications. Check datasheets for updated electrical characteristics regarding capacitance and resistance values at operating frequencies. Ensure compliance with environmental standards required for the intended application.

RF Diode Selection Notes

Select this component when a low-capacitance RF switch or attenuator is required in a small form factor. The 30V reverse voltage rating suits moderate RF power levels. Evaluate the 0.5pF capacitance specification for high-frequency signal integrity requirements. Consider the 125°C junction temperature limit for thermal management in dense PCB layouts.

RF Diode Part Context

This device belongs to the family of RF PIN diodes produced by Vishay. These components are distinct from standard rectifier or Zener diodes due to their variable resistance properties under RF excitation. The S391D-GS08 specifically targets applications requiring fast switching speeds and low insertion loss in microwave and radio frequency systems.
