CD5301

Current Regulation - Diodes, Transistors Overview

The CD5301 is a silicon current regulator diode manufactured by Microchip Technology. It provides a nominal regulation current of 1.4 mA with a maximum limiting voltage of 1.55 V. The device features a single configuration and is housed in an uncased chip package (DIE-1) with one terminal. It has a maximum power dissipation rating of 0.5 W and operates as a unidirectional component. The part is classified under the ECCN code EAR99 and is not RoHS compliant.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation at 1.4 mA
• Utilizes silicon semiconductor material
• Designed for surface mount integration via die-level packaging

Current Regulation - Diodes, Transistors Applications

• Current limiting circuits
• Biasing networks for electronic components
• Constant current sources in low-power applications

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific manufacturing lot and date code to ensure compliance with project requirements, as the component is noted as non-RoHS compliant. Confirm that the uncased die format aligns with the assembly capabilities of the target PCB design. Check for any specific handling instructions related to the bare die packaging to prevent damage during installation.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 1.4 mA current reference is required in a minimal footprint. Ensure the circuit input voltage does not exceed the 1.55 V maximum limiting voltage specification. Consider the 0.5 W power dissipation limit when designing thermal management strategies for the application environment.

Current Regulation - Diodes, Transistors Part Context

The CD5301 belongs to the category of discrete semiconductor diodes, specifically functioning as a current regulator. It is distinct from voltage regulators like the MIC5301 series also produced by Microchip. This component serves as a passive element for controlling current flow without active feedback loops.

Current Regulation - Diodes, Transistors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with alternative current regulator diodes based on identical 1.4 mA regulation and 1.55 V max voltage specifications.
