1N4695UR-1/TR

Overview

The Microchip Technology 1N4695UR-1/TR is a 0.5 W surface mount Zener diode in the DO-213AA package. It provides an 8.7 V nominal voltage with a standard ±5% tolerance and a test current of 50 µA. The device features a hermetically sealed glass construction with internal metallurgical bonding for high reliability. Electrical characteristics include a maximum reverse leakage current of 1.0 µA at 1.0 V and a maximum DC Zener current of 54.8 mA. Operating temperatures range from -65 °C to +175 °C.

Feature Summary

• Hermetically sealed glass DO-213AA (MELF style) surface mount package
• Internal metallurgical bond between metal slugs and silicon die
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic circuits requiring radiation hardness
• Surface mount equivalents for JEDEC registered axial-leaded series

Procurement Notes

Verify the specific suffix configuration against official documentation, as ordering codes determine RoHS compliance and screening levels. Confirm that the TR suffix indicates tape and reel packaging per EIA-481-1-B standards. Ensure compatibility with the intended manufacturing process regarding soldering temperatures and terminal plating options.

Selection Notes

Select this component when a 0.5 W surface mount Zener regulator is required with high reliability and radiation hardness. The internal metallurgical bond offers superior performance compared to standard commercial packages. Consider tighter voltage tolerances if available through specific part nomenclature suffixes.

Part Context

This device belongs to the 1N4678UR-1 thru 1N4717UR-1 series of 500 mW glass surface mount Zener voltage regulators. It serves as the surface mount equivalent to the JEDEC registered 1N4678 thru 1N4717 axial-leaded series. The series covers a voltage selection from 1.8 to 43 volts.

Replacement Considerations

The 1N4695UR-1 is the direct surface mount equivalent of the 1N4695-1 axial-leaded Zener diode.
