• Low saturation voltage for efficient switching performance
• Robust construction suitable for high-temperature applications up to 175°C

Single Bipolar Transistors Applications

• Power switching circuits
• Amplification stages requiring high current drive
• Industrial control systems operating at elevated temperatures

Single Bipolar Transistors Procurement Notes

Verify the specific suffix AZ against the official Renesas datasheet to confirm lead-free status and package variant. Ensure the procurement channel is authorized, as this part may be subject to restricted distribution or legacy support policies. Confirm that the TO-126 package dimensions match the design requirements before ordering.

Single Bipolar Transistors Selection Notes

Select this component when a high-current NPN BJT is required for switching or amplification. The low VCE(sat) characteristic makes it suitable for applications demanding minimal power loss during conduction. Consider the thermal management capabilities due to the 1.3 W dissipation limit and the potential for operation at temperatures up to 175°C.

Single Bipolar Transistors Part Context

This transistor belongs to Renesas' Bipolar Power Transistors family, which includes devices designed for high power and low saturation voltage applications. The 2SD1691 series is specifically engineered for robust performance in demanding environments, offering reliability for industrial and automotive-grade electronics where high current capacity is critical.

Single Bipolar Transistors Replacement Considerations

Check for direct substitutes within the 2SD1691 series or equivalent NPN transistors with matching 60V/5A ratings. Verify pinout compatibility for the TO-126 package. Note that availability may vary as some variants are supported only for existing customers.
