Overview
The BC857CWQ-7 is a PNP small signal transistor manufactured by Diodes Incorporated, designed for automotive applications. It operates in an SOT323 package with a collector-emitter voltage (VCEO) of -45 V and a collector-base voltage (VCBO) of -50 V. The device supports a continuous collector current (IC) of -100 mA and features a DC current gain (hFE) ranging from 420 to 800 at IC = -2 mA. Power dissipation is rated at 200 mW, with a transition frequency (fT) of 100 MHz. It meets AEC-Q101 standards and is fully RoHS compliant.
Feature Summary
- AEC-Q101 qualified for stringent automotive application requirements
- Ideally suited for automatic insertion processes
- Totally lead-free and fully RoHS compliant
- Halogen- and antimony-free green device
Applications
- Automotive switching circuits
- Audio frequency (AF) amplifier applications
- General-purpose amplification tasks
Procurement Notes
Verify the specific ordering suffix (-7 or -13) to confirm reel size and quantity per reel. Ensure that the K3G marking code matches the required product type identification. Confirm compliance with IATF16949 manufacturing standards if automotive change control protocols are mandatory for your supply chain.
Selection Notes
Select this component when designing for environments requiring high reliability and strict quality control standards. Consider its complementary NPN counterpart, the BC847CWQ, for push-pull configurations. Evaluate the thermal resistance and power dissipation limits against your expected ambient operating temperatures to ensure stable performance under load.
Part Context
This part belongs to the BC857 series of PNP general-purpose transistors produced by Diodes Incorporated. It is specifically engineered to meet automotive industry standards, distinguishing it from standard commercial-grade variants through its qualification and manufacturing certifications.
Replacement Considerations
The BC847CWQ serves as the complementary NPN type within the same family. Verify pinout compatibility and electrical characteristics before substituting with other SOT323 PNP transistors from different manufacturers.
FAQ
Is the BC857CWQ-7 suitable for high-voltage switching applications?
