Overview
The 1N5311UR-1 is a round-end current regulator diode manufactured by Microchip Technology. It operates in the surface-mount DO-213AB (MELF) package, designed for high-reliability applications. The device maintains a constant current of 3.96 mA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. It functions as a two-terminal solid-state current source, providing stable regulation across a wide temperature range suitable for harsh environments.
Feature Summary
- Provides precise constant current regulation without external components
- Utilizes a hermetically sealed glass MELF package for environmental protection
- Designed for high-temperature operation in demanding conditions
Applications
- Biasing circuits for transistors and active devices
- Constant current sources for LED drivers
- Reference current generation in analog signal processing
Procurement Notes
Verify the specific suffix UR-1 against the manufacturer's datasheet to confirm pinout orientation and electrical tolerances. Ensure the procurement channel provides traceability documentation required for military or aerospace specifications associated with this component series.
Selection Notes
Select this component when a fixed current sink is required in a compact surface-mount form factor. Compare the 3.96 mA nominal current against circuit requirements to ensure compatibility with load impedance and supply voltage limits defined in the electrical characteristics table.
Part Context
This part belongs to the 1N53xx series of round-end current regulator diodes. It shares functional similarities with through-hole equivalents like the 1N5311 but offers a smaller footprint via the DO-213AB package. The series is characterized by stable performance over extended temperature ranges.
Replacement Considerations
Direct substitutes include JANTX1N5311UR-1 and JANTXV1N5311UR-1 from Microchip, which offer enhanced radiation hardness or tighter tolerance specifications while maintaining identical electrical parameters and package dimensions.
