1N5284

Overview

The Microchip Technology 1N5284 is a current regulator diode designed for stable low-current applications. It features a maximum regulated current of 264µA and supports a peak operating voltage of 100V. The device has a maximum limit voltage of 1V and operates within a temperature range of -65°C to 175°C. Packaged in surface-mount format, it provides reliable current regulation without requiring external components.

Feature Summary

• Provides constant current regulation with minimal external circuitry requirements
• Operates reliably across extended industrial temperature ranges
• Supports high peak reverse voltage for flexible circuit integration

Applications

• Biasing circuits for sensors and transistors
• Current limiting protection in low-power electronics
• Reference current sources in analog signal processing

Procurement Notes

Verify the specific package type and tape-and-reel specifications against the official datasheet before ordering. Confirm that the supplier provides traceable documentation matching the manufacturer's part number. Ensure environmental compliance requirements align with project standards, as military-grade variants may have different qualification statuses than commercial equivalents.

Selection Notes

Select this component when a precise microampere-level current source is required in a compact surface-mount form factor. Evaluate the 100V peak voltage rating against the maximum circuit potential to ensure adequate safety margins. Consider the wide operating temperature range for environments subject to thermal extremes.

Part Context

The 1N5284 belongs to the CD528/1N528 series of current regulator diodes manufactured by Microchip Technology. This series offers various fixed current values tailored for precision biasing needs. The device represents a specialized discrete semiconductor solution distinct from standard rectifier or zener diodes.

Replacement Considerations

Cross-reference with other 1N528x series parts if different current levels are acceptable. Verify pinout compatibility and package dimensions before substituting with equivalent devices from other manufacturers.
