1N4133UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4133UR-1 is a Zener voltage regulator diode designed for surface mount applications. It utilizes the DO-213AA-2 package, which corresponds to the MELF (Metal Electrode Leadless Face) form factor. The device features an internal metallurgical bond, indicated by the "-1" suffix, ensuring robust mechanical integrity. It provides a nominal Zener voltage of 87V with a standard tolerance of 5%. The component is rated for a power dissipation of 0.5 W and operates within a temperature range extending from -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify the specific revision level and manufacturing date code upon receipt to ensure compliance with project requirements. Confirm that the DO-213AA-2 footprint matches the PCB layout exactly. Check for any specific handling instructions related to the glass body construction. Ensure storage conditions prevent moisture ingress prior to soldering. Validate all markings against the official datasheet specifications.

Single Zener Diodes Selection Notes

Select this component when a surface mount Zener diode with high thermal stability is required. The internal metallurgical bond distinguishes it from non-bonded variants, offering superior resistance to mechanical shock. Consider the 87V nominal voltage and 5% tolerance for precise regulation needs. Evaluate the 0.5W power rating against the expected load current in the target application circuit.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR-1 through 1N4135UR-1 series of 0.5-watt glass surface mount Zener diodes manufactured by Microchip. These devices are surface mount equivalents of JEDEC registered axial-leaded parts. The series offers voltages from 1.8 to 100 volts. Military qualifications such as JAN, JANTX, and JANTXV are available for these components.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4133UR-1 variants from different manufacturers if they meet the DO-213AA-2 package and electrical specifications. Verify pinout compatibility and thermal characteristics before substitution.
