1N6004UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N6004UR-1/TR is a surface mount Zener diode in the 1N5985BUR-1 through 1N6031BUR-1 series. It provides voltage regulation with a nominal Zener voltage of 15V at a test current of 5.0mA. The device features a maximum DC Zener current (IZM) of 600mA and operates within a junction temperature range of -65°C to +175°C. Packaged in a hermetically sealed glass DO-213AA (SOD-80/MELF-2) case, it offers internal metallurgical bonds and is available in tape and reel format.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF-style package with internal metallurgical bonds for high reliability
• Surface mount equivalent to JEDEC registered 1N5985 to 1N6031 series
• Minimal capacitance characteristics suitable for various operating conditions
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability applications requiring screening in reference to MIL-PRF-19500
• Environments requiring inherent radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix required for the application, as the 'B' suffix indicates a 5% Zener voltage tolerance. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS compliant versions are available on commercial grade only. Ensure the 'TR' suffix is included to secure the tape and reel packaging option rather than standard bulk or tube quantities.

Single Zener Diodes Selection Notes

Select this component when a 15V Zener voltage is needed in a surface mount form factor. The 0.5W power dissipation rating supports moderate current requirements up to 600mA. Consider the wide operating temperature range and radiation hardness for demanding environments. Verify thermal resistance values against the PCB footprint layout to ensure adequate heat dissipation under continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1N5985BUR-1 through 1N6031BUR-1 series of 0.5 watt Zener voltage regulators manufactured by Microsemi (now Microchip Technology). These devices serve as surface mount equivalents to the traditional axial-leaded JEDEC registered 1N5985 to 1N6031 series. The series covers a voltage selection from 2.4 to 200 volts with multiple tolerance options.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N6004 variants such as 1N6004DUR-1 or axial-leaded equivalents like 1N6004B. Verify package compatibility when substituting with non-MELF packages.
