Overview
The 2N5249 PBFREE is a single NPN general-purpose bipolar junction transistor manufactured by Central Semiconductor Corp. It utilizes silicon planar technology and is housed in a TO-92-3 through-hole package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 625 mW. The device operates within a temperature range of -65°C to +150°C.
Feature Summary
- Utilizes silicon planar technology for reliable performance
- Designed for general-purpose switching and amplification applications
- Compatible with standard through-hole mounting processes
Applications
- General-purpose signal amplification circuits
- Low-power switching applications
- Audio pre-amplifier stages
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Central Semiconductor or authorized distributors before procurement. Confirm that the TO-92-3 package dimensions match your PCB footprint requirements. Ensure that thermal management strategies account for the 625 mW power dissipation limit under expected operating conditions to maintain reliability.
Selection Notes
Select this component when a low-cost, general-purpose NPN transistor is required for low-current applications up to 100 mA. Consider the 50 V voltage rating to ensure it exceeds the maximum circuit voltages. Evaluate the TO-92-3 package for compatibility with existing assembly equipment and manual handling processes compared to surface-mount alternatives.
Part Context
This part belongs to the broader family of small-signal bipolar transistors produced by Central Semiconductor. It serves as a fundamental discrete semiconductor component used in various electronic assemblies. The designation indicates a lead-free manufacturing process compliant with environmental standards, distinguishing it from older legacy versions.
Replacement Considerations
Consult official substitution guides for direct equivalents such as the 2N5249 TRE variant if specific tape-and-reel packaging is required instead of bulk. Verify pinout compatibility and electrical parameter margins against other common NPN transistors like the 2N3904 or BC547, ensuring voltage and current ratings are sufficient for the target application.
