2N7053

Single Bipolar Transistors Overview

The onsemi 2N7053 is an NPN Darlington transistor designed for applications requiring extremely high gain at collector currents up to 1.0 A and high breakdown voltage. Manufactured using Process 06 technology, this component provides robust switching capabilities in a standard TO-92 package. It features a continuous collector current rating of 1.5 A and a collector-emitter breakdown voltage of 100 V. The device is suitable for general-purpose amplification and switching tasks where high current gain is critical.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source when ordering, as the 2N7053 designation has been produced by multiple semiconductor vendors including Fairchild Semiconductor and onsemi. Confirm that the received component matches the required Process 06 specifications if process-specific performance is critical for the design. Ensure the package type and pinout configuration align with the existing board layout before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select the 2N7053 when circuit requirements demand high current gain combined with moderate voltage handling. It serves as a direct replacement for other NPN Darlington transistors in legacy designs. Consider thermal management constraints due to power dissipation limits in the TO-92 package. Evaluate alternative packages if higher power handling or surface-mount integration is required for modern assembly processes.

Single Bipolar Transistors Part Context

The 2N7053 belongs to the family of NPN Darlington transistors, which integrate two bipolar junction transistors to achieve significantly higher current gain than single-transistor devices. This configuration allows for effective control of larger loads with minimal base drive current. The component is widely used in industrial and consumer electronics where reliable switching and amplification are necessary.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers include MPSA13, BC517, MMBT6427, TN6725A, and 2N5306. Verify electrical parameter compatibility, particularly gain and voltage ratings, before substituting these alternatives.
