1N2979RB

Overview

The Microchip Technology 1N2979RB is a 10-watt Zener diode with a nominal voltage of 15 V and ±5% tolerance. It features a maximum impedance of 3 Ohms and operates within a temperature range of -65°C to 175°C. The component utilizes a DO-213AA stud-mount package for robust thermal management.

Feature Summary

• High power dissipation capability of 10 watts for stable regulation under heavy loads
• Extended operating temperature range from -65°C to 175°C for harsh environments
• Stud-mount construction in DO-213AA package for efficient heat transfer

Applications

• High-power voltage regulation circuits
• Industrial control systems requiring wide temperature stability
• Military and aerospace electronic assemblies

Procurement Notes

Verify the specific suffix 'RB' against official Microchip documentation to confirm exact qualification levels, as variants may differ in testing standards or packaging. Ensure compatibility with existing thermal management designs due to the stud-mount form factor.

Selection Notes

Select this component when high power handling and wide temperature operation are required. The 15V nominal rating suits applications needing precise regulation at this level. Verify that the mounting hardware supports the stud-mount configuration and thermal requirements.

Part Context

This part belongs to the 1N2970B through 1N3015B series of 10W Zener diodes manufactured by Microchip Technology. These components are designed for reliable performance in demanding applications, offering regulated voltages across a broad spectrum.

Replacement Considerations

Check for direct equivalents within the same series, such as other 15V 10W Zener diodes from Microchip. Ensure any substitute matches the stud-mount package and electrical specifications exactly.
