1N4104-1

Single Zener Diodes Overview

The Microchip Technology 1N4104-1 is a 500 mW metallurgically bonded glass Zener diode in an axial-lead DO-35 package. It provides a nominal Zener voltage of 10 V with a standard tolerance of ±5%. The device operates at a test current of 250 µA and exhibits a maximum dynamic impedance of 0.5 Ω. Maximum reverse leakage current is specified at 7.6 µA, while the noise density is limited to 40 µV/√Hz. It supports a temperature coefficient of +0.080 %/°C and functions within a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for high reliability
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS levels
• Hermetically sealed glass DO-35 package
• Inherently radiation hard

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring radiation hardness
• Precision reference circuits utilizing low noise characteristics

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as qualification varies by suffix. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS versions are available on commercial grades only. Ensure the ordering part number matches the exact voltage tolerance and package style needed.

Single Zener Diodes Selection Notes

Select this component when a stable 10 V reference is required in harsh environments. The positive temperature coefficient makes it suitable for compensation applications where voltage increases with heat. Consider the low noise density for sensitive analog front ends. Verify power derating requirements against ambient temperatures exceeding 25 °C.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes manufactured by Microchip Technology. These components share common packaging and construction features but vary in nominal voltage from 1.8 V to 100 V. The series is designed for military and aerospace sectors requiring high reliability and radiation tolerance.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 10 V nominal voltage, 500 mW power rating, and DO-35 package. Verify that substitute parts meet the same MIL-PRF-19500/435 qualification levels if radiation hardness or extreme temperature operation is required.
