2N3839 TIN/LEAD

Overview

The 2N3839 TIN/LEAD is a small signal NPN silicon transistor manufactured by Central Semiconductor Corp. It is designed for general-purpose amplification and switching applications in electronic circuits. The device utilizes a through-hole mounting configuration within a TO-92-3 package, ensuring compatibility with standard PCB layouts. Key electrical characteristics include a maximum collector-emitter voltage of 40V and a continuous collector current rating of 200mA. The component supports a power dissipation of 625mW and operates effectively at frequencies up to 150MHz. It features a DC current gain (hFE) of at least 100 when tested at specific bias conditions.

Feature Summary

• Small signal NPN silicon construction optimized for low-power amplification tasks
• Through-hole TO-92-3 package design for reliable mechanical mounting
• High-frequency capability suitable for RF and audio signal processing

Applications

• General-purpose amplifier stages in consumer electronics

• Audio pre-amplification modules

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure material compliance. Confirm that the TIN/LEAD variant meets specific environmental regulations required for the target assembly process. Cross-reference the Central Semiconductor part number with distributor listings to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a small-signal NPN transistor with moderate voltage ratings and through-hole packaging is required. Ensure the application current does not exceed 200mA and power dissipation remains within 625mW limits. Consider thermal management requirements if operating near maximum ratings. Verify frequency response needs align with the 150MHz transition frequency specification.
