1N4100/TR

Single Zener Diodes Overview

The Microchip Technology 1N4100/TR is a 7.5 V Zener voltage regulator with a 200 Ohm impedance, housed in an axial-lead glass DO-35 package. It features a 5% voltage tolerance and operates within a -65°C to +175°C temperature range. The device dissipates up to 500 mW of power and includes a tape-and-reel packaging option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Internal metallurgical bond for high reliability
• Hermetically sealed glass construction
• Flexible axial-lead mounting terminals

Single Zener Diodes Applications

• Voltage regulation over broad current ranges
• High reliability military applications
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify that the TR suffix confirms tape-and-reel packaging per EIA-296 standards. Confirm the specific reliability level (JAN, JANTX, etc.) matches project requirements, as commercial versions differ from MIL-PRF-19500/435 qualified parts.

Single Zener Diodes Selection Notes

Select this component for circuits requiring stable voltage reference in harsh environments. Ensure thermal derating calculations account for ambient temperatures exceeding 25°C. Verify lead plating options if RoHS compliance is mandatory for the assembly process.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mW metallurgically bonded glass Zener diodes. These devices are JEDEC registered and available in various voltage tolerances and qualification levels including JAN, JANTX, and JANS.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4100-1, JANTX1N4100-1, and JANTXV1N4100-1. Surface mount alternatives are available in the 1N4100UR-1 series using the DO-213AA package.
