The 2N5818 APM PBFREE is a single NPN bipolar junction transistor manufactured by Central Semiconductor Corp. It utilizes silicon technology and features a TO-92-3 through-hole package. Key electrical specifications include a collector-emitter voltage (Vceo) of 40 V, a collector-base voltage (Vcbo) of 40 V, and an emitter-base voltage (Vebo) of 7.5 V. The device supports a maximum continuous collector current of 750 mA and dissipates up to 625 mW of power. It exhibits a transition frequency (fT) of 135 MHz.
Verify the specific suffix 'APM' against the manufacturer's official datasheet to confirm tin/lead composition requirements. Ensure the TO-92-3 package dimensions match the target PCB footprint. Confirm RoHS compliance status for the specific batch, as 'PBFREE' indicates lead-free but packaging variations may exist.
Select this component when a small-signal NPN transistor with moderate current handling capability is required. The 135 MHz transition frequency suits audio and low-frequency RF applications. Compare the 625 mW power dissipation limit against thermal constraints in the final assembly design.
This part belongs to the general-purpose BJT category from Central Semiconductor. It serves as a discrete active element for circuit control and signal processing. The TO-92-3 form factor allows for easy integration into prototyping boards and consumer electronics assemblies requiring standard through-hole components.
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic 2N5818 equivalents only if electrical parameters align exactly with the original specification sheet.
