Overview
The BC857AQBAZ is a PNP general-purpose bipolar junction transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 100 mA. The device utilizes silicon technology and is housed in a DFN-1110D-3 (SOT8015) leadless surface-mount package. Key electrical characteristics include a collector-base voltage of 45 V, a collector-emitter saturation voltage of 650 mV, and a maximum power dissipation of 200 mW. It features a transition frequency of 100 MHz and a DC current gain of at least 125 under specified conditions.
Feature Summary
- Leadless ultra-small plastic package design for efficient board space utilization
- AEC-Q101 qualified for automotive reliability standards
- Low package height to support compact electronic designs
Applications
- General-purpose small signal amplification
- Low and medium frequency AC applications
- Mobile device circuitry
Procurement Notes
Verify the specific suffix 'BAZ' against official Nexperia documentation to confirm the exact reel packaging configuration and manufacturing lot details. Ensure the DFN1110D-3 footprint matches the target PCB layout. Confirm RoHS compliance status through the manufacturer's restricted substances declaration before final procurement approval.
Selection Notes
Select this component when a leadless SMD package is required to minimize footprint area compared to traditional SOT-23 transistors. The AEC-Q101 qualification makes it suitable for automotive environments where high reliability is mandatory. Consider the 45 V rating for low-voltage switching or amplification tasks within mobile and consumer electronics systems.
Part Context
This part belongs to the BC857 series of PNP general-purpose transistors from Nexperia. It serves as the complement to the BC847 NPN series. The BC857AQBAZ variant specifically denotes the DFN1110D-3 package, distinguishing it from other package options like SOT-323 or SOT-883 within the same electrical family.
Replacement Considerations
Direct substitutes include other BC857 variants with identical electrical ratings but different packages, such as BC857AW (SOT-323). For pin-compatible replacements in the same package family, verify availability of other DFN1110D-3 parts. Cross-reference with BC857AM for similar performance in the DFN1006-3 package if slight dimensional changes are acceptable.
