1N4713UR-1/TR

Overview

The Microchip Technology 1N4713UR-1/TR is a 0.5 W surface mount Zener diode in the DO-213AA (MELF) package, featuring a nominal voltage of 30 V with a standard tolerance of ±5%. It operates within a junction temperature range of -65°C to +175°C and utilizes an internal metallurgical bond for high reliability. The device includes a tape and reel option indicated by the TR suffix.

Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bonding
• Surface mount equivalent of JEDEC registered 1N4678 through 1N4717 series
• 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 hermetic sealing
• Radiation-hardened applications

Procurement Notes

Verify that the specific part number matches the required tolerance level, as tighter tolerances require different suffixes. Confirm RoHS compliance status if applicable, noting it is available on commercial grade only. Ensure the tape and reel packaging aligns with automated assembly requirements.

Selection Notes

Select this component when a 30 V Zener reference is needed in a compact surface mount form factor. Consider the low test current of 50 µA for sensitive biasing conditions. Evaluate thermal resistance values against the expected power dissipation and ambient temperature constraints.

Part Context

This device belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 watt glass surface mount Zener voltage regulators. The series provides a selection from 1.8 to 43 volts with standard 5% tolerance options.

Replacement Considerations

Equivalent commercial versions are available in the DO-35 axial package format without the UR-1 suffix.
