BCP68

Overview

The BCP68 is an NPN medium power transistor manufactured by Philips Semiconductors, now part of NXP Semiconductors. It features a maximum collector current of 1 A and a low voltage rating of 20 V. The device has a minimum DC current gain (hFE) of 160 and a transition frequency of 40 MHz. It supports surface mount installation with a maximum power dissipation of 1.4 W and operates up to 150 °C.

Feature Summary

• Monolithic Darlington configuration for high current drive capability
• Low voltage operation suitable for compact circuits
• High current handling up to 1 A continuous
• Surface mount packaging for automated assembly

Applications

• General purpose switching applications
• Low voltage amplifier stages
• Driver circuits for small loads

Procurement Notes

Verify the manufacturer designation carefully, as the component is originally from Philips Semiconductors and subsequently associated with NXP Semiconductors. Confirm the package type matches the specific surface mount requirement. Ensure the voltage and current ratings align with the target circuit design before procurement.

Selection Notes

Select this component for applications requiring moderate current switching at low voltages. The high current gain simplifies base drive requirements. Consider the thermal management capabilities given the 1.4 W power dissipation limit in the chosen package.

Part Context

This transistor belongs to the medium power discrete semiconductor category. It serves as a general-purpose NPN device within the broader portfolio of bipolar transistors offered by NXP and its predecessor Philips. It complements other low-voltage switching solutions in industrial and consumer electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent NPN Darlington transistors having similar 1 A and 20 V ratings.
