1N4133UR

Single Zener Diodes Overview

The Microchip Technology 1N4133UR is a surface mount Zener voltage regulator featuring a glass DO-213AA package. It provides an 87V nominal Zener voltage with a standard 5% tolerance and a maximum dynamic impedance of 1000 Ohms. The device is rated for 500mW power dissipation and operates within a junction temperature range of -65°C to 175°C. This component serves as the non-bonded surface mount equivalent to the JEDEC registered 1N4133 axial-leaded series.

Single Zener Diodes Feature Summary

• Surface mount construction in a glass DO-213AA package
• Internal metallurgical bond option available with the -1 suffix
• Qualified for military standards including JAN, JANTX, and JANTXV levels

Single Zener Diodes Applications

• Voltage regulation in high-reliability electronic circuits
• Reference voltage sources in aerospace systems
• Protection circuits requiring stable breakdown voltage

Single Zener Diodes Procurement Notes

Verify the specific qualification level required for your application, as the base part number may differ from military-qualified variants like JANTX or JANTXV. Confirm whether the internal metallurgical bond (suffix -1) is necessary for your design, as this affects mechanical reliability under shock and vibration. Ensure the DO-213AA footprint matches your PCB layout constraints.

Single Zener Diodes Selection Notes

Select this component when a surface mount Zener diode with an 87V breakdown voltage is needed. Consider the JANTX or JANTXV variants if military-grade reliability is mandated. The -1 suffix indicates an internally bonded structure suitable for harsh environments. Verify that the 500mW power rating meets the thermal requirements of your specific circuit design.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zener diodes manufactured by Microchip. These components are designed as direct surface mount replacements for traditional axial-leaded JEDEC registered parts. The series offers voltages ranging from 1.8V to 100V with various tolerance options.
