Overview
The JAN1N2992B is a military-grade Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 39V and a maximum current rating of 65mA. The device exhibits an impedance of 11 ohms and utilizes a stud-mount package configuration. This component belongs to the 1N2970B through 1N3015B series, which are qualified per MIL-PRF-19500/124 standards for high-reliability applications.
Feature Summary
- Hermetically sealed welded construction with internal solder bond design
- Qualified under JAN, JANTX, and JANTXV military specifications
- Designed for robust voltage regulation in demanding environments
Applications
- Military electronic systems requiring high reliability
- Aerospace voltage regulation circuits
- Harsh environment power supply protection
Procurement Notes
Verify the specific qualification grade (JAN, JANTX, or JANTXV) required for your application, as availability varies by grade. Confirm that the stud-mount package fits your mechanical constraints. Check for current manufacturing status as these are often special order items. Ensure compatibility with existing thermal management solutions for stud-mounted components.
Selection Notes
Select this component when a 39V regulation point is needed in a ruggedized system. The stud-mount style offers superior thermal dissipation compared to axial leads. Consider the 11-ohm impedance for noise-sensitive designs. Verify that the 65mA current limit meets the circuit's peak load requirements without exceeding the device's absolute maximum ratings.
Part Context
This part is part of the 1N2970B–1N3015B series of 10W Zener diodes. These devices are JEDEC registered and available in standard and reverse polarities. The series supports voltage regulation values ranging from 3.9V to 200V. Microchip provides surface mount equivalents upon request for modern packaging needs.
Replacement Considerations
Direct substitutes include other 39V Zener diodes in stud-mount packages from qualified manufacturers. Ensure any replacement matches the 65mA current rating and 11-ohm impedance. Verify that alternative parts meet the same MIL-PRF-19500/124 qualification levels if military compliance is mandatory.
