1N4101 (DO35)

Single Zener Diodes Overview

The Microsemi Corporation 1N4101 (DO35) is a silicon Zener diode with a nominal voltage of 8.2 V and a standard tolerance of ±5%. It operates in the axial-lead glass DO-35 package, rated for a maximum power dissipation of 0.5 W at 25 °C lead temperature. The device features an internal metallurgical bond and supports a junction temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Hermetically sealed construction using an internal metallurgical bond within a glass DO-35 package.
• Low noise density performance, specified at 40 μV/√Hz at the test current.
• Inherently radiation hard design suitable for high reliability applications.

Single Zener Diodes Applications

• Voltage regulation across broad ranges of current and temperature.
• High reliability circuits requiring MIL-PRF-19500/435 qualification levels.
• Radiation-hardened electronic systems.

Single Zener Diodes Procurement Notes

Verify the specific reliability level required, as the component is available in JAN, JANTX, JANTXV, and JANS qualifications per MIL-PRF-19500/435. Confirm RoHS compliance status, as commercial versions are available with an e3 suffix while military grades may differ. Ensure the ordering suffix matches the desired tolerance and packaging configuration.

Single Zener Diodes Selection Notes

Select this component for applications requiring stable voltage reference or regulation in harsh environments. The 8.2 V rating fits within the series range of 1.8 to 100 V. Consider the low capacitance and minimal noise characteristics for sensitive signal paths. Verify thermal derating requirements if operating above ambient temperatures.

Single Zener Diodes Part Context
