BC517,112

Single Bipolar Transistors Overview

The BC517,112 is an NPN Darlington transistor manufactured by NXP Semiconductors. It is housed in a TO-92 (SOT54) plastic package with three terminals. The device supports a maximum collector current of 0.5 A and a collector-emitter voltage of 30 V. It features a minimum DC current gain (hFE) of 30000. The component operates at a maximum junction temperature of 150 °C and complies with RoHS standards.

Single Bipolar Transistors Feature Summary

• High current capability up to 500 mA
• Very high DC current gain for significant amplification
• Low voltage operation suitable for sensitive circuits

Single Bipolar Transistors Applications

• Applications requiring very high amplification
• General purpose switching and amplification tasks

Single Bipolar Transistors Procurement Notes

Verify the specific ordering code BC517,112 against official NXP documentation to ensure correct package type and compliance status. Confirm that the TO-92 form factor matches the design requirements. Check for any specific handling instructions related to the plastic epoxy packaging material during assembly processes.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN device provides sufficient gain without cascading multiple transistors. The high hFE rating makes it suitable for low-level signal amplification. Ensure the 30 V voltage limit accommodates the circuit's peak operating conditions. Consider the TO-92 package constraints for thermal management and board space.

Single Bipolar Transistors Part Context

This part belongs to the BC517 series of NPN Darlington transistors. It serves as the complement to the BC516 PNP variant. The series is designed for general-purpose applications where high gain and moderate current handling are required. NXP manufactures this component using standard silicon planar epitaxial technology.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include MPSA13, MMBT6427, and 2N5306. Verify pinout compatibility and electrical parameters such as current gain and voltage ratings before substitution. Ensure the replacement device meets the same RoHS compliance requirements.
