BA679-GS18

Overview

The BA679-GS18 is a single RF PIN diode manufactured by Vishay Semiconductors, housed in the MiniMELF SOD-80 surface-mount package. It features a minimum breakdown voltage of 30 V and a nominal capacitance of 0.5 pF. The device operates within a wide frequency range from 10 MHz to 1 GHz. Electrical characteristics include a maximum forward resistance of 5000 Ω tested at 100 MHz. The component is AEC-Q101 qualified for automotive applications and supports a maximum operating temperature of 125 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Wide operational frequency range spanning 10 MHz to 1 GHz
• Miniature MiniMELF SOD-80 surface-mount packaging

Applications

• Current controlled attenuators
• HF resistance in adjustable circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements and packaging options. The GS18 suffix indicates availability on a 13-inch reel with 10,000 units per box. Confirm material categorization and RoHS status directly from the manufacturer's datasheet or product change notifications prior to procurement.

Selection Notes

Select the BA679 variant over the BA679S when a lower maximum forward resistance of 5000 Ω is required, as the BA679S specifies 8000 Ω. Ensure the design accommodates the 30 V breakdown voltage and 0.5 pF capacitance limits. Verify that the SOD-80 package dimensions fit the PCB layout constraints for the intended high-frequency application.

Part Context

This component belongs to Vishay's series of RF PIN diodes designed for miniaturized applications. The BA679 family offers consistent performance across the 10 MHz to 1 GHz spectrum. The SOD-80 case provides a compact footprint suitable for dense circuit board designs while maintaining the electrical integrity required for radio frequency signal processing tasks.
