Procurement Notes
Verify the manufacturer part number against official onsemi documentation to ensure authenticity. Confirm that the component meets RoHS3 compliance standards and check for any specific marking layout updates resulting from Fairchild Semiconductor integration. Ensure sourcing through authorized distributors to avoid counterfeit parts.
Selection Notes
Select this component when designing N-channel RF amplifier circuits requiring low noise performance at frequencies around 400 MHz. Verify that the required drain current falls within the 5 mA to 15 mA range and that the operating voltage does not exceed the 15 V rating. Consider the SOT-23 package constraints for PCB layout.
Part Context
The MMBF4416A is part of the MMBF4416 series of N-channel RF amplifiers. Originally produced by Fairchild Semiconductor, it is now managed under onsemi following corporate integration. The device maintains its original specifications and functionality while adhering to updated ordering nomenclature standards.
Replacement Considerations
Consult the official onsemi website for updated ordering information and potential cross-references. Verify compatibility with existing circuit designs before substituting with other JFETs or RF amplifiers.
