Overview
The BC857BTQ-7 is a PNP small signal Bipolar Junction Transistor (BJT) manufactured by Diodes Incorporated. It utilizes epitaxial planar die construction and is housed in an ultra-small SOT-523 surface-mount package. The device is qualified to AEC-Q101 standards for automotive applications and supports PPAP requirements. Key electrical parameters include a collector-emitter breakdown voltage of -45V, a maximum DC collector current of -100mA, and a power dissipation rating of 150mW at 25°C ambient temperature. The transition frequency is specified at 100MHz.
Feature Summary
- Qualified to AEC-Q101 standards for high reliability in automotive environments
- Utilizes epitaxial planar die construction within an ultra-small SOT-523 package
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green compound
- Capable of PPAP submission for automotive supply chain integration
Applications
- Automotive general-purpose switching and amplification circuits
- Signal processing in compact electronic assemblies
- Complementary pairing with BC847BTQ NPN transistors
Procurement Notes
Verify the specific ordering suffix '-7' corresponds to the standard 3,000-unit reel quantity as defined in the manufacturer's documentation. Confirm that the component marking '3W' matches the intended date code and production batch for traceability purposes. Ensure the procurement channel is authorized to guarantee compliance with the stated AEC-Q101 qualification and PPAP capabilities required for automotive-grade components.
Selection Notes
Select this component when designing for space-constrained applications requiring a PNP transistor with automotive-grade reliability. The SOT-523 package offers a smaller footprint compared to standard SOT-23 variants while maintaining similar electrical characteristics. Consider the complementary BC847BTQ if an NPN counterpart is needed for push-pull or differential configurations within the same automotive qualification framework.
Part Context
This part belongs to the BC857 series of PNP small signal transistors produced by Diodes Incorporated. The 'BTQ' designation indicates the specific SOT-523 packaging and automotive qualification status. It serves as the PNP complement to the BC847BTQ NPN transistor, allowing for matched performance in dual-transistor applications. The series is engineered to meet stringent automotive industry standards for durability and consistency.
Replacement Considerations
Direct substitutes include other AEC-Q101 qualified PNP transistors in the SOT-523 package from Diodes Incorporated, such as the BC857BS variant, provided pinout compatibility and thermal resistance specifications are verified against the original design constraints.
