1N4710UR-1/TR

Overview

The Microchip Technology 1N4710UR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 25.0 V and a standard tolerance of ±5%. It operates within a power dissipation limit of 0.5 W and features a hermetically sealed DO-213AA glass package. The device utilizes an internal metallurgical bond for high reliability and maintains a low Zener test current of 50 µA. It supports a junction temperature range from -65°C to +175°C.

Feature Summary

• Hermetically sealed glass surface mount construction
• Internal metallurgically bonded die structure
• Low capacitance design suitable for sensitive circuits
• Inherently radiation hard performance

Applications

• Voltage regulation over broad operating ranges
• ESD protection in electronic systems
• Radiation-hardened circuit designs
• Temperature-compensated reference applications

Procurement Notes

Verify the specific suffix configuration against official documentation, as ordering codes determine RoHS compliance and tolerance levels. Confirm that the TR suffix indicates tape and reel packaging per EIA-481-1-B standards. Ensure compatibility with MIL-PRF-19500 screening requirements if high-reliability up-screening is necessary for the intended application environment.

Selection Notes

Select this component when a compact surface mount solution is required for precise voltage regulation. The DO-213AA package offers a direct footprint equivalent to the traditional JEDEC registered through-hole series. Consider the low leakage current and tight voltage tolerance options if the design demands high stability under varying thermal conditions or strict regulatory constraints.

Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5-watt Zener diodes. The series provides a wide selection of voltages ranging from 1.8 V to 43.0 V. These devices are designed as surface mount equivalents to established JEDEC registered types, maintaining similar electrical characteristics while offering improved mechanical robustness and automated assembly compatibility.

Replacement Considerations

Direct replacements include other manufacturers' DO-213AA (SOD80/MLL34) packaged Zener diodes rated at 25 V with ±5% tolerance. Verify that substitute components meet the same 0.5 W power dissipation and -65°C to +175°C operating temperature specifications.
