1N4134

Single Zener Diodes Overview

The Microchip Technology 1N4134 is a Zener voltage regulator with a nominal breakdown voltage of 91 V. It operates within the 1N4099-1 through 1N4135-1 series and features a maximum power dissipation of 500 mW. The device utilizes an internal metallurgical bond and is housed in a hermetically sealed axial-lead glass DO-35 (DO-204AH) package. Electrical characteristics include a maximum Zener impedance of 1200 Ohms, a test current of 250 µA, and a maximum reverse leakage current of 0.01 µA at 69.2 V. The component supports a junction temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Constructed with an internal metallurgical bond for structural integrity.
• Hermetically sealed in an axial-lead glass DO-35 package.
• Capable of regulating voltage across broad ranges of current and temperature.
• Inherently radiation hard.

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring MIL-PRF-19500/435 qualification

Single Zener Diodes Procurement Notes

Verify the specific reliability level required, as the base JEDEC number corresponds to commercial grade. Military qualifications such as JAN, JANTX, JANTXV, and JANS require distinct ordering suffixes. Confirm RoHS compliance status, as it applies only to commercial versions. Ensure the correct tolerance suffix matches the design requirements.

Single Zener Diodes Selection Notes

Select based on the required Zener voltage tolerance, available in standard 5%, 2%, and 1% variations. Verify the operating environment against the specified thermal resistance and derating curves. Consider the package type if surface mount alternatives are needed, as the series also includes DO-213AA and DO-216 options.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mW metallurgically bonded glass Zener diodes. The series covers voltages from 1.8 V to 100 V and is qualified per MIL-PRF-19500/435. Commercial versions are available in tape and reel formats.

Single Zener Diodes Replacement Considerations

Equivalent part numbers include JANS1N4134-1, JANTX1N4134-1, and JANTXV1N4134-1, which share the same electrical specifications but differ in reliability qualification levels.
