1N4715UR-1/TR

Overview

The Microchip Technology 1N4715UR-1/TR is a 0.5 W surface mount Zener diode in a hermetically sealed glass DO-213AA (SOD-80) package. It provides a nominal Zener voltage of 36 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C and features a Zener test current of 50 µA. The 'TR' suffix indicates tape and reel packaging per EIA-481-1-B.

Feature Summary

• Hermetically sealed glass MELF-style package for environmental protection
• Internal metallurgical bond between metal slugs and silicon die
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard construction

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic assemblies requiring radiation hardness
• Surface mount equivalents for JEDEC registered through-hole designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm tolerance, plating, and screening levels. Confirm RoHS compliance status as it varies by commercial grade availability. Ensure the 'TR' suffix matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when a 36 V Zener reference is required in a compact surface mount form factor. Consider the internal metallurgical bonding for applications demanding high reliability. Verify that the 0.5 W power dissipation rating and thermal resistance values are sufficient for the target PCB footprint and ambient conditions.

Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 W Zener voltage regulators. The series covers voltages from 1.8 V to 43 V in the DO-213AA package. These devices serve as surface mount equivalents to the traditional JEDEC registered 1N4678 through 1N4717 axial leaded series.

Replacement Considerations

Direct replacements include other manufacturers' DO-213AA Zener diodes rated at 36 V with similar power dissipation. Cross-reference with the 1N4715 axial leaded series if through-hole mounting is acceptable.
