BC639-16-BP

Single Bipolar Transistors Overview

The BC639-16-BP is an NPN epitaxial silicon transistor manufactured by Micro Commercial Components (MCC). It features a TO-92 package with a maximum collector-emitter voltage of 80 V and a continuous collector current rating of 1 A. The device offers a power dissipation capacity of 1 W at 25°C, degrading linearly to zero at 125°C ambient temperature. The BC639-16 variant specifies a DC current gain (hFE) range of 100 to 250 when tested at a collector current of 150 mA and a collector-emitter voltage of 2 V. It includes a thermal resistance of 125°C/W from junction to ambient.

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix matches the required binning specifications. The standard part number indicates bulk packaging containing 100,000 pieces per carton. Confirm the presence of the specific hFE grading suffix corresponding to the desired gain range. Ensure compliance with environmental directives if halogen-free variants are required for the project.

Single Bipolar Transistors Selection Notes

Select this component based on the required collector current and voltage ratings for the target circuit. The BC639-16 designation specifically denotes a higher current gain bin compared to lower-numbered variants. Evaluate the thermal management requirements against the specified junction-to-ambient resistance. Verify that the TO-92 through-hole package aligns with the printed circuit board layout constraints.

Single Bipolar Transistors Part Context

This transistor belongs to the broader BC639 family of NPN medium-power devices produced by various semiconductor manufacturers. The specific MCC version utilizes a standard TO-92 axial leaded plastic package. It serves as a common replacement in legacy designs requiring robust NPN switching capabilities within low-voltage environments.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC639-16 from other manufacturers such as NXP or onsemi. Cross-referencing datasheets is necessary to confirm identical pinout configurations and electrical parameter tolerances before implementation.
