1N3996A

Single Zener Diodes Overview

The Microchip Technology 1N3996A is a commercial-grade Zener diode with a nominal voltage of 6.8 V and a power dissipation rating of 500 mW. It features a 10% voltage tolerance, a maximum reverse leakage current of 2 µA, and a Zener impedance of 25 ohms at a test current of 5 mA. The device operates within a temperature range of -65°C to +175°C and utilizes an axial DO-35 package.

Single Zener Diodes Feature Summary

• Hermetically sealed construction with internal solder bond for reliability
• Zener regulation capability across standard voltage values
• Qualified per MIL-PRF-19500/124 standards for military grades

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Overvoltage protection applications
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application, as these military grades are available on most voltage values within the series. Confirm that the commercial version meets your environmental requirements if military qualification is not necessary. Ensure the axial DO-35 package fits your board layout constraints.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V regulation point is needed with moderate power handling. Consider the 10% tolerance for precision requirements. Verify thermal management capabilities given the 500 mW dissipation limit. Check if the extended operating temperature range suits your environment.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N3993A through 1N3998A series of 10 W Zener diodes, though the 1N3996A specifically is rated for 500 mW in commercial packages. The series offers voltages from 3.9 V to 200 V and supports both standard and reverse polarities.

Single Zener Diodes Replacement Considerations

Consult the manufacturer for surface mount equivalents if space constraints require a different package type. Other parts in the 1N3996 series may offer different voltage ratings but share similar construction characteristics.
