Overview
The BC857BQCZ is a PNP general-purpose transistor manufactured by Nexperia. It operates with a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device utilizes an ultra-small DFN1412D-3 (SOT8009) leadless surface-mounted package featuring side-wettable flanks for enhanced soldering reliability. This component serves as the PNP complement to the BC847BQC NPN transistor within the same series.
Feature Summary
- Ultra-small leadless SMD plastic package design
- Side-wettable flanks for improved solder joint visibility
- General-purpose switching and amplification capability
Applications
- General-purpose small signal DC applications
- Low and medium frequency AC applications
- Mobile device circuitry
Procurement Notes
Verify the specific suffix 'Z' against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the ordering part number matches the exact electrical characteristics required for the target application. Cross-reference the datasheet revision date to confirm compliance with current RoHS directives and material declarations before finalizing procurement orders.
Selection Notes
Select this component when board space constraints require an ultra-small footprint compared to standard SOT23 packages. The DFN1412D-3 package offers power dissipation comparable to larger packages while reducing overall board area. Consider the matched BC847BQC counterpart if complementary NPN/PNP pairs are needed for differential or push-pull configurations in the design.
Part Context
This part belongs to the BC857 family of PNP transistors, which includes variants like BC857AQC and BC857CQC distinguished by hFE gain ranges. The BC857BQCZ specifically denotes the B-grade gain binning within the DFN1412D-3 package format. It is designed for high-volume consumer electronics manufacturing where miniaturization and automated placement efficiency are critical priorities.
Replacement Considerations
Direct pin-compatible replacements include other BC857B variants in different packages such as BC857BQ or BC857BW, provided the package dimensions fit the PCB layout. Verify that alternative manufacturers' equivalents meet the 45V VCEO and 100mA IC specifications.
