BA979-GS08

RF Diode Overview

The BA979-GS08 is a single RF PIN diode manufactured by Vishay General Semiconductor - Diodes Division, housed in the QuadroMELF SOD-80 surface-mount package. It operates within a wide frequency range of 10 MHz to 1 GHz and is qualified under AEC-Q101 standards. Key electrical parameters include a maximum reverse voltage of 30 V, a forward continuous current rating of 50 mA, and a typical diode capacitance of 0.5 pF at 100 MHz with zero bias. The device exhibits a differential forward resistance of 50 Ω at 100 MHz and 1.5 mA forward current, alongside a minority carrier lifetime of 4 μs.

RF Diode Feature Summary

• AEC-Q101 automotive qualification for enhanced reliability
• QuadroMELF SOD-80 plastic case construction
• Wide operational frequency range from 10 MHz to 1 GHz

RF Diode Applications

• Current controlled HF resistance in adjustable attenuators

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ordering suffix GS08 corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Ensure compliance with relevant regional material regulations before final procurement integration.

RF Diode Selection Notes

Select this component when high-frequency signal attenuation control is required in compact designs. The SOD-80 package facilitates space-constrained PCB layouts. Verify that the 30 V reverse voltage and 50 mA forward current ratings align with the specific circuit operating conditions and thermal management capabilities of the target application environment.

RF Diode Part Context

This part belongs to the BA979 series of RF PIN diodes produced by Vishay Semiconductors. The series includes variants such as the BA979S, which offers higher reverse impedance. These components are designed specifically for radio frequency applications requiring precise current-controlled resistance characteristics within small form-factor packages.

RF Diode Replacement Considerations

BA979S-GS08 provides similar functionality but features a reverse impedance greater than 9 kΩ compared to the standard BA979's 5 kΩ minimum.
