CD5286 is listed in the Current Regulation - Diodes, Transistors range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is DIODE CUR REG 100V 330UA. Review the specifications below when checking this part for your BOM.
The CD5286 is a silicon current regulator diode manufactured by Microchip Technology. It provides a nominal regulation current of 0.3 mA with a maximum limiting voltage of 1 V. The device features a single-diode configuration and is designed for surface-mount installation in an uncased chip package. It operates within a temperature range of -65°C to 175°C and has a maximum power dissipation of 0.5 W.
Verify the specific manufacturer documentation for the CD5286 to confirm compliance status, as some records indicate non-lead-free or unqualified certification states. Ensure the selected variant matches the required surface-mount package type and thermal specifications for the intended application environment.
Select the CD5286 when a fixed low-current regulation value near 0.3 mA is required. Consider the 1 V maximum voltage drop and 0.5 W power dissipation limits during circuit design. Verify that the uncased chip package format aligns with the available board space and assembly capabilities.
The CD5286 belongs to the CD528 family of current regulator diodes from Microchip Technology. This series includes variants with different regulation currents, such as the CD5284 which offers 264 µA. These components serve as simple, passive alternatives to active current sources in low-power applications.
Check datasheets for other members of the CD528 family, such as the CD5284, if alternative current values are acceptable. Verify pinout and package compatibility before substituting any similar current regulator diodes.
