Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The '/TR' designation indicates tape and reel packaging, which differs from bulk options. Confirm RoHS compliance status as it varies by grade. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current value near 0.82 mA is required in a compact surface-mount footprint. Consider the 10% current tolerance and the 100 V peak operating voltage limit during circuit design. Evaluate thermal derating requirements if ambient temperatures exceed 125 °C. Compare against axial-leaded equivalents if through-hole mounting is mandatory.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283UR-1 through 1N5314UR-1 series of 0.5 W current regulators. These devices serve as surface-mount equivalents to the traditional 1N5283 through 1N5314 axial series. The family offers a wide selection of currents ranging from 0.22 mA to 10.0 mA, providing designers with standardized options for various current regulation needs.

Current Regulation - Diodes, Transistors Replacement Considerations

The 1N5295 (axial) serves as the direct leaded equivalent. For surface-mount replacements, verify that alternative current regulator diodes match the 0.82 mA nominal current and DO-213AB package dimensions. Ensure substitute parts meet the same 100 V peak voltage and 500 mW power dissipation ratings.
