Overview
The 1N2979B is a 10 W Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device operates within a temperature range of -65°C to 175°C and utilizes a stud-mount configuration in the DO-213AA (DO-4) package. Key electrical characteristics include a maximum Zener impedance of 3 Ohms and a forward voltage of 1.5 V at 2 A. Reverse leakage current is specified as 10 µA at 11.4 V.
Feature Summary
- High power dissipation capability of 10 W for robust voltage regulation
- Extended operating temperature range from -65°C to 175°C
- Stud-mount construction for efficient thermal management
- Qualified per MIL-PRF-19500/124 standards
Applications
- Military and aerospace electronic systems
- Industrial power supply voltage regulation
- High-reliability circuit protection
Procurement Notes
Verify the specific qualification level required for your application, as this component series includes JAN, JANTX, and JANTXV grades alongside commercial versions. Confirm that the base part number 1N2979 corresponds to the desired military or commercial specification before ordering. Ensure the mounting hardware supports the stud-mount package type for proper installation.
Selection Notes
Select this component when high power handling and wide temperature stability are critical. The 15 V rating suits mid-range reference applications. Consider the physical size of the DO-4 package for PCB or chassis layout constraints. Verify that the 3 Ohm impedance meets the dynamic regulation requirements of the target circuit design.
Part Context
This device belongs to the 1N2970B through 1N3015B series of 10 Watt Zener diodes produced by Microchip. These components are JEDEC registered and offer voltage regulation values ranging from 3.9 V to 200 V. The series is engineered for durability in demanding environments, providing a reliable solution for power electronics where standard low-power diodes would fail.
Replacement Considerations
Check for exact cross-reference availability from other manufacturers offering equivalent 10 W, 15 V Zener diodes in DO-4 packages. Ensure any substitute matches the ±5% tolerance and thermal resistance specifications. Military-grade replacements must meet the same MIL-PRF-19500/124 qualification levels.
