The 2N5961 APM PBFREE is an N-channel Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor. It features a maximum drain-source voltage of 40V and a gate-source voltage rating of 40V. The device operates with a continuous drain current of 100mA and offers a typical forward transconductance of 3000µS at a drain current of 10mA. It is housed in a TO-92 package and is designed for general-purpose amplification and switching applications.
Verify the specific electrical parameters against the official datasheet before integration, as manufacturing tolerances may vary. Confirm that the TO-92 through-hole package aligns with your PCB footprint requirements. Ensure the Pb-free soldering profile complies with the manufacturer's recommended thermal guidelines to maintain device integrity during assembly.
Select this component when a discrete JFET solution is required for high-input-impedance applications. Compare its 40V breakdown voltage and 100mA current limits against circuit demands. Consider the TO-92 package size for through-hole mounting constraints. Evaluate the transconductance specifications to ensure adequate gain for the intended signal path.
This part belongs to the family of small-signal N-channel JFETs produced by Central Semiconductor. These devices are commonly used in analog electronics where high input impedance and low noise are critical. The APM suffix indicates the Ammo Pack packaging format, which is standard for through-hole components in industrial and commercial electronic assemblies.
