1N3986

Single Zener Diodes Overview

The Microchip Technology 1N3986 is a 10W Zener diode with a nominal voltage of 6.2V and a 5% tolerance. It utilizes silicon technology in a unidirectional configuration, housed in a DO-4 metal stud mount package with a solder lug terminal. The device operates at a test current of 805 mA and features internal solder bond construction within a hermetically sealed welded housing.

Single Zener Diodes Feature Summary

• Hermetically sealed welded construction for environmental protection
• Internal solder bond construction for mechanical reliability
• Stud mount design for efficient thermal dissipation

Single Zener Diodes Applications

• Military and aerospace power supply regulation
• High-reliability industrial voltage reference circuits
• Harsh environment protection systems

Single Zener Diodes Procurement Notes

Verify the specific qualification grade (JAN, JANTX, or JANTXV) required for your application, as military grades are available per MIL-PRF-19500/124. Confirm that the DO-4 stud mount package and solder lug interface match your board layout and thermal management requirements before ordering.

Single Zener Diodes Selection Notes

Select this component when high power handling (10W) and strict environmental sealing are necessary. Ensure the system can accommodate the stud mount form factor and provides adequate heat sinking. Verify that the 6.2V regulation point aligns with the circuit design needs.

Single Zener Diodes Part Context

This part belongs to the 1N3993A through 1N3998A series of 10W Zener diodes manufactured by Microchip Technology. These devices are JEDEC registered and designed for applications requiring robust voltage regulation in demanding conditions, often serving as replacements for older military-grade components.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 10W Zener diodes with 6.2V nominal voltage in DO-4 packages, such as the 1N3986E3 from Microsemi. Ensure any replacement maintains the same hermetic sealing and stud mount specifications.
