1N4101-1

Single Zener Diodes Overview

The Microchip Technology 1N4101-1 is a 500 mW metallurgically bonded glass Zener diode in the axial-lead DO-35 package. It provides an 8.2 V nominal Zener voltage with a standard ±5% tolerance. 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 6.3 µA at 6.92 V, a dynamic impedance of 0.5 Ohms, and a positive temperature coefficient of +0.070 %/°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 military qualification
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple qualification grades. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS versions are available on commercial grade only. Ensure the ordering suffix matches the desired termination plating and packaging format.

Single Zener Diodes Selection Notes

Select this component when a stable 8.2 V reference is needed in harsh environments. The positive temperature coefficient makes it suitable for higher voltage Zener applications. Consider the low dynamic impedance for noise-sensitive circuits. Verify thermal derating requirements if operating above ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes manufactured by Microsemi/Microchip Technology. These devices are JEDEC registered and designed for robust performance in demanding electronic systems. The series offers a wide selection of voltages from 1.8 V to 100 V with various tolerance options.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 8.2 V Zener voltage, 500 mW power rating, and DO-35 package. Verify equivalent MIL-PRF-19500/435 qualification levels if military-grade reliability is required. Cross-reference dynamic impedance and leakage current specifications to ensure circuit compatibility.
