Overview
The BC857CQB-QZ is a PNP general-purpose bipolar junction transistor manufactured by Nexperia. It utilizes silicon technology and is housed in a DFN1110D-3 (SOT8015) leadless surface-mount package. The device supports a maximum collector-emitter voltage of 45 V and a collector-base voltage of 45 V. It features a low collector-emitter saturation voltage of 650 mV at specified currents. The component is designed for SMD/SMT installation and is supplied in reel, cut tape, or MouseReel formats.
Feature Summary
- Leadless ultra-small plastic package design with side-wettable flanks to enhance solder joint visibility and reliability.
- Low collector-emitter saturation voltage capability suitable for efficient switching applications.
- RoHS compliant construction utilizing standard silicon process technology.
Applications
- General-purpose small signal DC amplification
- Low and medium frequency AC applications
- Mobile device circuitry
Procurement Notes
Verify the specific suffix QZ against official Nexperia documentation to confirm package dimensions and marking codes. Confirm current production status as related BC857 variants have faced discontinuation notices. Ensure compatibility with automated pick-and-place equipment due to the leadless DFN form factor. Validate RoHS compliance requirements for the target assembly process.
Selection Notes
Select this component when board space is constrained and high-density mounting is required. The DFN1110D-3 package offers a smaller footprint compared to traditional SOT-23 packages while maintaining comparable power dissipation characteristics. Consider the 45 V voltage rating for low-voltage signal processing tasks. Verify thermal management needs as the leadless package relies on pad conduction for heat dissipation.
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 BC857C variant specifically denotes a minimum DC current gain range. The QBZ/QZ suffix indicates the specific DFN1110D-3 packaging configuration used for compact electronic designs.
Replacement Considerations
BC857CQBZ is a direct equivalent part number within the same product family. BC857CW,115 offers similar electrical characteristics but uses an SOT-323 package. BC857C,215 provides identical functionality in a standard SOT-23 package. Verify pinout compatibility before substituting across different package types.
