CD5287

Current Regulation - Diodes, Transistors Overview

The CD5287 is a current regulator diode manufactured by Microchip Technology. It provides a regulated output current of 363µA with a maximum voltage rating of 100V between the anode and cathode. The device operates within a temperature range of -65°C to 175°C and is designed for surface mount installation. It belongs to the CD528 series, which offers current regulation capabilities similar to Zener diodes but across a broad voltage range. The component is RoHS compliant and currently in production.

Current Regulation - Diodes, Transistors Feature Summary

• High source impedance for consistent performance
• Suitable for surface mount applications

Current Regulation - Diodes, Transistors Applications

• Current limiting circuits
• Constant current sources
• Biasing networks for semiconductor devices

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific package type and tape/reel specifications against the official datasheet before ordering. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure compliance with RoHS directives if required by the end product regulations.

Current Regulation - Diodes, Transistors Selection Notes

Select the CD5287 when a fixed current of 363µA is required. Consider the 100V maximum voltage rating to ensure it exceeds the circuit's peak reverse voltage. Evaluate the surface mount package suitability for the PCB layout constraints compared to axial-leaded alternatives in the same series.

Current Regulation - Diodes, Transistors Part Context

The CD5287 is part of the CD5283 through CD5314 series of current regulator diodes from Microchip Technology. This series provides various current levels ranging from 0.22 mA to 4.7 mA. These devices serve as counterparts to Zener diodes, regulating current rather than voltage, and are available in both commercial and military-qualified versions depending on the suffix.

Current Regulation - Diodes, Transistors Replacement Considerations

Check for direct substitutes within the CD528 series with different current ratings if 363µA is not exact. Verify pinout compatibility for any cross-brand replacements. Military-grade equivalents may require specific qualification standards like MIL-PRF-19500/463.
