Overview
The BA679S-M-08 is a PIN diode manufactured by Vishay General Semiconductor - Diodes Division. It features a minimum breakdown voltage of 30 V and a nominal diode capacitance of 0.5 pF. The device has a maximum forward resistance of 8000 Ω measured at a test frequency of 100 MHz. It supports surface mount installation and operates at a maximum temperature of 125 °C. The component utilizes Tin/Lead (Sn/Pb) terminal plating and carries the JESD-609 code e0.
Feature Summary
- PIN diode structure for high-frequency switching applications
- Surface mount package design for automated assembly
- Low nominal capacitance for signal integrity
Applications
- RF switching circuits
- Attenuator modules
- High-frequency signal processing
Procurement Notes
Verify the specific ordering suffix to confirm compliance with current environmental directives, as the base model data indicates non-RoHS status. Confirm that the tin/lead terminal finish meets the target assembly requirements. Ensure the 125 °C maximum operating temperature aligns with the thermal management strategy of the final equipment design before procurement.
Selection Notes
Select this component when a low capacitance value of 0.5 pF is required for high-frequency operation. The 30 V breakdown voltage defines the reverse bias limits. Compare the 8000 Ω forward resistance against circuit loss tolerances. Verify that the surface mount form factor fits the available PCB real estate constraints.
Part Context
This part belongs to the Vishay PIN diode family, sharing core electrical characteristics with the standard BA679 model. The primary distinction lies in the packaging and suffix designation, which dictates the physical mounting style. Both variants maintain identical baseline performance metrics regarding breakdown voltage and capacitance.
Replacement Considerations
The BA679 serves as a direct functional substitute with identical electrical parameters. Verify that the alternative package type accommodates the existing footprint. Confirm that the lead-free or leaded terminal finish of the replacement matches the soldering process capabilities.
