Overview
The BA679-M-18 is a single RF PIN diode manufactured by Vishay Semiconductors, housed in the MiniMELF SOD-80 surface-mount package. It features a breakdown voltage of 30 V and a nominal capacitance of 0.5 pF. The device supports a wide frequency range from 10 MHz to 1 GHz. It is AEC-Q101 qualified for automotive reliability. The standard BA679 variant specifies a reverse resistance greater than 5 kΩ at 100 MHz. Packaging options include GS18 (10K per reel) and GS08 (2.5K per reel).
Feature Summary
- AEC-Q101 qualified for automotive applications.
- Wide frequency operation from 10 MHz to 1 GHz.
- MiniMELF SOD-80 surface-mount case.
Applications
- Current controlled attenuators.
- HF resistance in adjustable circuits.
Procurement Notes
Verify the specific suffix against official documentation, as the provided knowledge base lists BA679-GS18 and BA679-GS08. Confirm availability status, as some variants are marked as discontinued or have limited supply. Ensure the ordering code matches the required packaging quantity and tape specifications for production integration.
Selection Notes
Select the BA679 variant if the application requires a reverse resistance greater than 5 kΩ. Choose the BA679S variant only if a reverse resistance exceeding 9 kΩ is necessary. Verify that the SOD-80 package dimensions fit the PCB layout constraints. Ensure the 30 V breakdown voltage meets the circuit's peak reverse voltage requirements.
Part Context
This component belongs to the Vishay BA679 series of RF PIN diodes designed for high-frequency signal control. The series offers miniaturized solutions in the MiniMELF SOD-80 package. These diodes are engineered for consistent performance across a broad frequency spectrum, supporting both commercial and automotive electronic designs requiring precise RF attenuation or switching.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Cross-referencing with other manufacturers requires independent verification of electrical parameters and package compatibility.
