Overview
The 2N5815 PBFREE is a single PNP bipolar junction transistor manufactured by Central Semiconductor Corp. It is designed for through-hole mounting in the TO-92-3 (TO-226AA) package. The device features a maximum collector-emitter voltage of 40 V and a collector-base voltage of 50 V. It supports a maximum DC collector current of 750 mA to 1 A and an emitter-base voltage of 5 V. The transition frequency is rated at 100 MHz, with a maximum power dissipation of 625 mW. The operating junction temperature range extends from -65°C to 150°C.
Feature Summary
- PNP small-signal high-current configuration suitable for general switching applications
- Lead-free construction compliant with RoHS standards
- Robust thermal performance with a wide operating junction temperature range
Applications
- General purpose switching circuits
- Small signal amplification stages
- Complementary transistor pairs in audio or logic circuits
Procurement Notes
Verify that the specific order line item explicitly states 'PBFREE' to ensure lead-free compliance. Confirm the package designation matches TO-92-3 or TO-226AA requirements. Check manufacturer datasheets for exact electrical limits regarding collector current and power dissipation before integration into final designs.
Selection Notes
Select this component when a PNP small-signal transistor with moderate current handling is required. The TO-92-3 package offers compact through-hole mounting. Ensure the application voltage does not exceed 40 V and current demands remain within the 750 mA to 1 A limit. Consider complementary NPN counterparts if paired operation is needed.
Part Context
This part belongs to the 2N5815 series of bipolar transistors produced by Central Semiconductor Corp. It serves as a standard small-signal PNP device for through-hole PCB assembly. The series is often utilized in consumer electronics and industrial control systems where reliable switching and amplification are necessary.
Replacement Considerations
Direct substitutes may include other PNP transistors in the TO-92 package with similar voltage and current ratings, such as the 2N5401 or 2N5881, provided pinout compatibility and electrical parameters meet the circuit requirements.
