1N4711/TR

Overview

The Microchip Technology 1N4711/TR is a single Zener diode with a nominal voltage of 27 V and a power dissipation of 500 mW. It features a ±5% voltage tolerance and operates in the DO-7 (DO-204AA) through-hole package. Key electrical parameters include a maximum reverse leakage current of 10 nA at 20.4 V, a test current of 1 mA, and a Zener impedance of 200 Ohms. The device supports an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Temperature compensated design for stable voltage regulation
• High stability with low noise characteristics
• Through-hole axial lead configuration for robust mounting

Applications

• Voltage stabilization circuits
• Temperature compensated reference applications
• General purpose regulation

Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging when ordering. Confirm the manufacturer is Microchip Technology, as other vendors produce similar part numbers. Ensure the DO-7 package style matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring precise voltage regulation over wide temperature ranges due to its temperature compensation feature. The 500 mW rating suits moderate current loads. Verify that the 200 Ohm Zener impedance meets the dynamic performance needs of the circuit design.

Part Context

This part belongs to the Microchip Technology single Zener diode family. It is distinct from non-compensated variants by its specific thermal coefficient properties. The /TR suffix denotes reel packaging, differentiating it from bulk or tube options within the same electrical specification set.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 27 V, 500 mW, and temperature compensated specifications precisely.
