1N3998A

Single Zener Diodes Overview

The Microchip Technology 1N3998A is a 10W Zener diode with a nominal voltage of 6.2V and ±5% tolerance. It features a maximum impedance of 1.1 Ohms and operates within a temperature range of -65°C to 175°C. The device utilizes a DO-213AA (DO-4) stud-mount package, offering high power dissipation capabilities for robust voltage regulation applications.

Single Zener Diodes Feature Summary

• Hermetically sealed welded construction for environmental protection
• Internal solder bond construction for mechanical reliability
• Qualified per MIL-PRF-19500/124 standards

Single Zener Diodes Applications

• Military grade voltage regulation circuits
• High-power reference voltage sources
• Industrial equipment requiring wide temperature operation

Single Zener Diodes Procurement Notes

Verify the specific qualification grade (JAN, JANTX, or JANTXV) required for your application, as availability varies by voltage value. Confirm RoHS compliance status, as this component may not meet current environmental directives. Ensure mounting hardware matches the DO-213AA stud configuration for proper thermal and electrical connection.

Single Zener Diodes Selection Notes

Select the 1N3998A when a 6.2V regulation point is needed with 10W power handling in a stud-mount form factor. Consider the low impedance characteristic for stable performance under varying load conditions. Verify that the operating environment supports the specified temperature range and hermetic sealing requirements.

Single Zener Diodes Part Context

This component belongs to the 1N3993A through 1N3998A series of 10W Zener diodes manufactured by Microchip Technology. These devices are designed for high-reliability applications and are often qualified to military specifications. The series offers a wide range of voltage values from 3.9V to 200V in a standardized package.

Single Zener Diodes Replacement Considerations

Check for direct equivalents within the 1N399x series or other manufacturers' 10W stud-mount Zener diodes with identical 6.2V ratings and DO-4 packages. Ensure any substitute meets the same MIL-PRF-19500/124 qualification if military-grade reliability is required.
