Overview
The JANTXV1N5309UR-1 is a current regulator diode manufactured by Microchip Technology, designed for surface-mount applications. It operates within the MIL-PRF-19500/463 military specification series. The device features a round-end SMT package in the DO-213AB-2 form factor. Key electrical parameters include a maximum voltage rating of 100V and a regulated current of 3.3mA. The component supports a power dissipation of 500mW and functions across an extended temperature range from -65°C to +175°C.
Feature Summary
- Military-grade reliability compliant with MIL-PRF-19500/463 standards
- Surface-mount construction utilizing a round-end glass MELF package
- Constant current regulation capability for stable circuit operation
Applications
- Precision constant current sources in aerospace systems
- Current limiting protection in high-reliability electronic circuits
- Biasing elements for sensitive semiconductor devices in extreme environments
Procurement Notes
Verify the specific suffix UR-1 against official Microchip documentation to confirm the reel packaging configuration and exact manufacturing lot details. Ensure compatibility with MIL-PRF-19500/463 quality requirements before integration into defense or space-grade hardware designs.
Selection Notes
Select this component when a robust, surface-mount current regulator is required for harsh environments. The DO-213AB-2 package offers compact mounting solutions compared to axial leads. Confirm that the 3.3mA regulation value aligns with the target circuit's biasing needs and thermal management constraints.
Part Context
This part belongs to the 1N5309 family of current regulator diodes produced under the JANTXV designation, indicating enhanced military screening. It shares functional similarities with other members like JANTX1N5309UR-1 but adheres to stricter qualification criteria defined by the V suffix for space and military use cases.
Replacement Considerations
JANTX1N5309UR-1 serves as a related variant within the same product line. Verify if the lower screening level of the TX suffix meets project requirements. No direct cross-brand substitutes are confirmed in public documentation.
