1N4134B/TR

Single Zener Diodes Overview

The Microchip Technology 1N4134B/TR is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides a nominal Zener voltage of 91 V with a standard tolerance of ±5%. The device operates within a junction and storage temperature range of -65 °C to +175 °C. Key electrical characteristics include a maximum reverse current of 10 µA, a dynamic impedance of 1200 Ohms, and a maximum noise density of 40 µV/√Hz at the test current of 250 µA.

Single Zener Diodes Feature Summary

• Metallurgically bonded construction for high reliability
• Hermetically sealed glass DO-35 axial-lead package
• Capable of regulating voltage across broad ranges of current and temperature

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• High-reliability applications qualified per MIL-PRF-19500/435
• Temperature-compensated regulator designs

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the 'TR' suffix to confirm tape and reel packaging compliance with EIA-296 standards. Ensure the required reliability level (JAN, JANTX, JANTXV, or JANS) matches the project specifications, as these are available options for this series. Confirm RoHS compliance status if applicable, noting that commercial grade versions may differ from military qualifications.

Single Zener Diodes Selection Notes

Select this component when a 91 V Zener voltage with ±5% tolerance is required in an axial-lead glass package. Consider the 500 mW power dissipation rating and the operating temperature range up to +175 °C. Evaluate the 1200 Ohm dynamic impedance and low leakage current against circuit requirements. Verify that the metallurgical bond construction meets the necessary environmental and radiation hardness criteria.

Single Zener Diodes Part Context

This device belongs to the 1N4099 through 1N4135 series of 500 mW Zener diodes manufactured by Microchip Technology. These components are JEDEC registered and offer extensive voltage selections from 1.8 to 100 volts. The series is designed for flexible mounting and robust performance in demanding electronic environments.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include the 1N4134-1 and 1N4134UR-1. Ensure replacement parts maintain the same voltage tolerance, package style, and reliability qualification levels.
