BCW72,215

Overview

The BCW72,215 is an NPN general-purpose transistor manufactured by Nexperia USA Inc. housed in a SOT23 plastic surface-mount package. It features a low collector current of 100 mA and a maximum collector-emitter voltage of 45 V. The device offers a DC current gain (hFE) range of 200 to 450 at IC = 2 mA and VCE = 5 V. Key electrical characteristics include a transition frequency of 100 MHz and a noise figure of 10 dB under specified conditions.

Feature Summary

• Low current capability with a maximum rating of 100 mA
• Low voltage operation with a collector-emitter voltage limit of 45 V
• Designed for low noise performance suitable for sensitive signal applications

Applications

• General purpose switching
• Amplification circuits

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the component status aligns with production availability requirements. Ensure the datasheet version corresponds to the most recent revision issued by Nexperia. Validate that the SOT23 package dimensions meet the target PCB footprint specifications.

Selection Notes

Select this component when a small-signal NPN transistor with moderate gain is required. The BCW72 variant provides higher current gain compared to the BCW71. Consider the thermal resistance and power dissipation limits during circuit design. Verify compatibility with the intended operating temperature range for the application environment.

Part Context

This part belongs to the BCW71/BCW72 series of NPN general-purpose transistors. It serves as the high-gain counterpart to the BCW71 within the same package family. The PNP complements for this series are the BCW69 and BCW70. These devices are widely used in standard discrete semiconductor applications requiring reliable switching and amplification.

Replacement Considerations

Direct substitutes include the BCW71 for lower gain requirements or other generic NPN transistors in the SOT23 package with matching voltage and current ratings. Verify pinout compatibility and ensure thermal characteristics align with the original design constraints before implementation.
