2SA1743-AZ

Single Bipolar Transistors Overview

The 2SA1743-AZ is a power PNP bipolar junction transistor manufactured by NEC (now Renesas Electronics). It features a maximum collector current of 10 A and a collector-emitter breakdown voltage of 60 V. The device is constructed from silicon and housed in a plastic/epoxy flange mount package with three through-hole terminals. Designed for switching applications, it has a minimum DC current gain of 60 and an isolated case connection.

Single Bipolar Transistors Feature Summary

• High current handling capability suitable for power switching loads
• Robust thermal management via flange mount packaging
• Isolated case design for simplified mounting on heatsinks

Single Bipolar Transistors Applications

• General purpose power switching circuits
• Industrial control systems requiring high current PNP transistors
• Power supply output stages

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the component was originally produced by NEC before its semiconductor division became part of Renesas. Confirm the specific suffix AZ matches the required datasheet revision. Ensure the flange mount package dimensions align with your mechanical design constraints before ordering.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 10 A continuous current capacity and 60 V voltage rating is required. The flange mount package is appropriate for applications needing direct heatsink attachment without insulators due to the isolated case. Consider the minimum hFE of 60 for base drive calculations in switching designs.

Single Bipolar Transistors Part Context

This component belongs to the family of power bipolar transistors historically produced by NEC Semiconductor. Following corporate restructuring, these products are managed under Renesas Electronics. The 2SA series typically denotes PNP silicon transistors designed for general-purpose and power switching applications in industrial and consumer electronics.

Single Bipolar Transistors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings if considering alternative manufacturers' PNP power transistors with similar 10A/60V specifications.
