Overview
The BC817-25-AU_R1_000A1 is a silicon NPN general-purpose transistor from the BC817-AU series manufactured by Panjit International Inc. It operates with a collector-emitter voltage of 45V and a continuous collector current of 500mA, housed in an SOT-23 package. The device features a DC current gain (hFE) range of 160 to 400 at IC=100mA and VCE=1V. It is qualified under AEC-Q101 standards for automotive applications and complies with EU RoHS 2.0 directives using lead-free technology.
Feature Summary
- Utilizes silicon NPN epitaxial planar design for robust performance
- Provides excellent DC current gain characteristics suitable for amplification
- Complies with environmental standards including EU RoHS 2.0 and IEC 61249 green molding compound requirements
Applications
- General purpose amplifier circuits
- Switching applications requiring low power dissipation
- Automotive electronic systems meeting AEC-Q101 qualification
Procurement Notes
Verify the specific suffix AU_R1_000A1 against official Panjit documentation to confirm packaging and marking details. Ensure procurement channels provide valid traceability via lot numbers as specified in manufacturer disclaimers. Confirm compliance with AEC-Q101 automotive grade requirements if deploying in vehicle electronics. Cross-reference datasheet revision REV.04S for accurate electrical limits.
Selection Notes
Select this component when a standard NPN transistor with moderate current handling and defined gain bands is required. The BC817-25 variant offers a specific hFE window of 160-400, distinguishing it from the -16 and -40 variants. Consider the SOT-23 footprint constraints and thermal resistance of 375°C/W for heat management in compact designs.
Part Context
This part belongs to the BC817-AU series of silicon NPN general-purpose transistors. It serves as the complementary counterpart to the BC807-AU PNP series. The series is designed for surface mount assembly, offering a compact solution for modern PCB layouts while maintaining reliability through AEC-Q101 certification.
Replacement Considerations
Direct substitutes within the same family include BC817-16-AU and BC817-40-AU, which share identical mechanical and maximum rating specifications but differ in DC current gain ranges. Verify pinout compatibility and thermal characteristics before substitution.
