2N4058 APM PBFREE is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is 30V 200MA 625MW TH TRANSISTOR-SM. Review the specifications below when checking this part for your BOM.
The 2N4058 APM PBFREE is a silicon N-channel Junction Field-Effect Transistor (JFET) manufactured by Central Semiconductor Corp. It features a maximum drain-to-gate voltage of 40V and a gate-source reverse voltage rating of 40V. The device supports a continuous drain current of up to 50mA with a power dissipation limit of 360mW. It utilizes the TO-92-3 through-hole package configuration.
Verify the specific suffix 'APM' against the manufacturer's official datasheet to confirm pinout orientation and mechanical dimensions, as packaging variants may differ. Ensure the 'PBFREE' designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the Mouser or DigiKey part numbers with the original component documentation to validate authenticity before procurement.
Select this component when a robust N-channel JFET with moderate current handling is required for discrete amplifier designs. Compare its 40V breakdown ratings against circuit supply voltages to ensure adequate safety margins. Evaluate the thermal constraints imposed by the 360mW dissipation limit within the intended enclosure environment.
This device belongs to the standard JFET family produced by Central Semiconductor Corp. It serves as a discrete alternative to integrated JFET arrays, offering flexibility in custom biasing networks. The TO-92-3 package allows for easy prototyping on breadboards and standard PCB layouts common in educational and industrial electronics.
