Overview
The 2N5249 TRE PBFREE is a PNP silicon epitaxial planar transistor manufactured by Central Semiconductor Corp. It is housed in a TO-92 (TO-226AA) through-hole package and supplied in a tape-and-reel configuration. The device features a collector-emitter breakdown voltage of 80V, a collector-base voltage of 80V, and an emitter-base voltage of 7V. It supports a continuous collector current of 500mA with a maximum power dissipation of 625mW. The component operates within a junction temperature range of -65°C to +150°C and complies with RoHS standards.
Feature Summary
- Utilizes silicon epitaxial planar technology for stable performance
- Designed for general-purpose switching and amplification applications
- Constructed in a standard TO-92 three-lead axial leaded package
Applications
- General-purpose low-power switching circuits
- Small-signal amplification stages
- Driver circuits for loads requiring moderate current handling
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm the reel packaging format. Ensure that the requested quantity aligns with the manufacturer's standard reel multiples. Confirm RoHS compliance status directly from the official datasheet prior to integration into environmentally regulated assemblies.
Selection Notes
Select this component when a PNP transistor with 80V collector-emitter capability and 500mA current rating is required in a TO-92 package. Consider the 625mW power dissipation limit and the specified operating temperature range during thermal design. Verify pinout compatibility with existing PCB footprints before finalizing the selection.
Part Context
This part belongs to the family of small-signal bipolar junction transistors produced by Central Semiconductor Corp. These devices are engineered for reliable operation in consumer electronics and industrial control systems. The 2N5249 variant specifically addresses applications needing PNP polarity with moderate voltage and current specifications in a compact through-hole form factor.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent 2N5249 specifications. Verify that substitute parts match the 80V VCEO, 500mA IC, and TO-92 package dimensions to ensure mechanical and electrical interchangeability without circuit modification.
