Overview
The BC857CW is a single PNP general-purpose bipolar junction transistor manufactured by Diotec Semiconductor. It utilizes an SOT-323 surface-mount package and operates with a maximum collector current of 100 mA and a power dissipation rating of 200 mW. The device features a collector-emitter breakdown voltage (VCEO) of -30 V, a collector-base voltage (VCBO) of -30 V, and an emitter-base voltage (VEBO) of -5 V. It supports a junction temperature range from -55°C to +150°C. The component belongs to the Group C current gain category, offering a DC current gain (hFE) range of 420 to 800 at -IC = 2 mA and -VCE = 5 V.
Feature Summary
- Single PNP epitaxial planar design for signal processing and switching applications
- Three distinct current gain groups available for precise amplification control
- Compliant with RoHS directives and REACH regulations without exemptions
Applications
- General purpose signal processing circuits
- Electronic switching functions
- Amplifier stages in commercial and industrial equipment
Procurement Notes
Verify the specific suffix designation when ordering, as it determines compliance status and moisture sensitivity level. Confirm that the required current gain group matches the application needs, as the BC857CW corresponds to the highest gain tier within the series. Ensure the procurement documentation references the correct marking code '3G' for identification during assembly.
Selection Notes
Select this component for designs requiring a compact SOT-323 footprint with high current gain characteristics. It serves as the complementary counterpart to the BC847W NPN transistor. Designers should account for the -30 V voltage limit and ensure thermal management aligns with the 200 mW dissipation capability under standard PCB mounting conditions.
Part Context
This part belongs to the BC856AW through BC859CW series of SMD general-purpose PNP transistors. The series provides various voltage ratings and gain groupings to suit different circuit requirements while maintaining a standardized mechanical outline. The BC857CW specifically targets applications needing moderate voltage handling combined with high amplification factors.
