BC857-QVL

Overview

The BC857-QVL is a PNP general-purpose bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. It is housed in an SOT-23 (TO-236AB) surface-mount package. The device features a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 100 mA. Key electrical parameters include a transition frequency of 100 MHz, a DC current gain of at least 125 at specific test conditions, and a power dissipation rating of 250 mW. The component operates within a temperature range up to 150°C.

Feature Summary

• PNP general-purpose bipolar junction transistor
• Qualified for automotive applications under AEC-Q101 standards
• Leadless ultra-small surface-mount plastic package design

Applications

• General-purpose small signal switching
• Low and medium frequency AC applications
• Mobile device circuitry

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact binning or tape-and-reel specifications. Ensure that the procurement channel provides valid traceability for automotive-grade components. Cross-reference the ordering code with the manufacturer's latest datasheet to avoid discrepancies in package type or qualification status.

Selection Notes

Select this component when a PNP BJT with 45V breakdown and 100mA current capacity is required in an SOT-23 footprint. Consider the AEC-Q101 qualification if the application demands automotive reliability standards. Compare thermal performance and gain characteristics against alternative packages like SOT-323 if board space constraints differ.

Part Context

This part belongs to the BC857 series of PNP transistors from Nexperia, designed as general-purpose small-signal devices. The series includes variants in different packages such as SOT-23, SOT-323, and DFN types. The BC857-QVL specifically denotes the SOT-23 variant qualified for automotive use, complementing the NPN BC847-QVL.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified PNP transistors in the SOT-23 package with matching 45V and 100mA ratings. Verify pinout compatibility and thermal resistance values before substitution.
