Procurement Notes

Verify the current manufacturing status before procurement planning. The component is listed as obsolete by Fairchild Semiconductor and subsequently acquired by onsemi. Confirm availability through authorized distributors or alternative sourcing channels. Ensure that the specific ordering suffix matches the required package and environmental specifications for the intended application.

Selection Notes

Select this component for designs requiring an N-Channel JFET with specific RF amplifier characteristics. Consider the absolute maximum ratings, particularly the 30 V voltage limits and thermal resistance values. Evaluate the electrical parameters such as IDSS and VGS(off) against circuit requirements. Verify compatibility with the TO-92-3 package for through-hole mounting.

Part Context

The 2N5950 is an N-Channel RF Amplifier originally manufactured by Fairchild Semiconductor. The part number 2N5950_J35Z indicates a specific variant within the product line. Fairchild Semiconductor was later acquired by onsemi, which now manages the product portfolio. This component belongs to the discrete semiconductor category, specifically RF FETs and MOSFETs.

Replacement Considerations

Check for direct equivalents from other manufacturers offering similar N-Channel JFET specifications. Verify pinout compatibility and electrical parameter overlaps. Consider the obsolete status when evaluating long-term supply chain stability for replacement options.
