Overview
The JANTX1N2997RB is a hermetically sealed, stud-mount Zener diode manufactured by Microchip Technology. It provides a nominal regulation voltage of 51V with a maximum reverse current of 50mA and an impedance of 15 ohms. The component features internal solder bond construction and is qualified to the JANTX military grade per MIL-PRF-19500/124 specifications.
Feature Summary
- Hermetically sealed welded construction for environmental protection
- Internal solder bond construction for mechanical stability
- Qualified to JANTX military standards
Applications
- Military-grade voltage regulation circuits
- High-reliability power supply reference designs
- Harsh environment electronic systems
Procurement Notes
Verify the specific revision level and lot traceability requirements against the latest manufacturer datasheet before procurement. Confirm that the JANTX qualification meets the project's reliability standards. Ensure proper mounting torque and thermal interface materials are selected for the stud-mount package to maintain performance under operational conditions.
Selection Notes
Select this component when military-grade reliability and hermetic sealing are required for voltage regulation applications. The stud-mount package facilitates efficient heat dissipation and secure mechanical attachment. Verify that the 51V regulation point and 15-ohm impedance align with the circuit design requirements.
Part Context
This part belongs to the 1N29xx series of 10-watt Zener diodes offered by Microchip Technology. The series includes various voltage ratings between 3.9V and 200V. The JANTX suffix indicates a higher reliability grade compared to commercial versions, suitable for demanding aerospace and defense applications.
Replacement Considerations
Consult the manufacturer for surface mount equivalents if space constraints require alternative packaging. Verify compatibility with JAN or JANTXV grades if different tolerance levels are needed.
