1N4100D-1

Single Zener Diodes Overview

The Microchip Technology 1N4100D-1 is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides a nominal Zener voltage of 7.5 V with a tight tolerance of ±1%. The device operates within a temperature range of -65°C to +175°C and features a maximum dynamic impedance of 200 Ohms at a test current of 250 µA.

Single Zener Diodes Feature Summary

• Internal metallurgical bond for high reliability
• Hermetically sealed glass DO-35 package
• Qualified per MIL-PRF-19500/435 standards

Single Zener Diodes Applications

• High-reliability military applications
• Voltage regulation over broad current ranges
• Temperature-stable reference circuits

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level, as commercial versions differ from MIL-qualified parts. Confirm RoHS compliance status if environmental regulations apply, noting that certain suffixes may indicate non-compliant plating. Ensure the procurement documentation explicitly references the correct JEDEC type number and tolerance code.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5 V reference with ±1% tolerance is required in an axial-lead form factor. The internal metallurgical bond supports operation across extreme temperatures up to 175°C. Consider the low noise density characteristics for sensitive analog signal paths requiring stable breakdown voltages.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener regulators. These devices are designed for rugged environments and offer extensive voltage selection from 1.8 V to 100 V. The 'D' suffix specifically denotes the 1% voltage tolerance variant available in this family.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4100-1, JANTX1N4100-1, and JANS1N4100-1. Verify that substitute components maintain the same 1% tolerance and MIL-PRF-19500/435 qualification level to ensure compatibility with existing designs.
