Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging rather than bulk, as standard JANTX variants often ship in bulk. Confirm the manufacturer's current production status and lead times directly with Microchip Technology, as military-grade components may have extended availability windows. Ensure compliance with all relevant export control classifications and quality certifications required for your specific procurement jurisdiction before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 30V regulation point is required within an axial through-hole form factor. The JANTX grade offers enhanced screening compared to commercial parts, making it suitable for defense and industrial sectors. Consider the 40 Ohm impedance and 8.5mA test current to ensure compatibility with your biasing network. Verify that the DO-41 package dimensions fit your PCB layout constraints and thermal management requirements effectively.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JANTX designation signifies a screened military-grade component that meets rigorous performance criteria beyond standard commercial specifications. These devices are typically utilized in applications where long-term stability and resistance to extreme environmental stressors are paramount design considerations.

Single Zener Diodes Replacement Considerations

Direct replacements include other JANTX series Zener diodes with identical 30V ratings and DO-41 packages, such as JAN1N3031D-1. Cross-reference datasheets to confirm matching impedance and leakage specifications. Ensure any substitute maintains the same MIL-PRF-19500 qualification level if military-grade reliability is required for the application.
