CDLL5299 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 1.32MA 500MW. Review the specifications below when checking this part for your BOM.
The CDLL5299 is a current-regulating diode manufactured by Microchip Technology, designed for applications requiring stable current limiting. It features a maximum anode-to-cathode voltage of 100 V and regulates current at a maximum of 1.32 mA. The device operates within a temperature range of -55°C to +175°C and dissipates up to 475 mW of power. It is housed in a DO-204AA (DO-7) axial through-hole package with a maximum forward voltage of 1.45 V.
Verify the specific manufacturer part number against official Microchip Technology documentation to ensure authenticity. Confirm that the DO-7 axial package matches the design requirements. Check RoHS compliance status as indicated in the product specifications before finalizing procurement orders.
Select this component when a fixed current limit near 1.32 mA is required without complex feedback loops. Ensure the circuit voltage does not exceed the 100 V maximum rating. Consider the 475 mW power dissipation capability relative to ambient thermal conditions during operation.
This component belongs to the Microchip Technology discrete semiconductor family, specifically categorized under current-regulating diodes. It serves as a passive alternative to active current sources, offering simplicity in design while maintaining reliable performance in harsh environments typical of industrial and automotive electronics.
Consult the official Microchip datasheet for cross-reference information. Verify electrical compatibility regarding current regulation values and voltage ratings before substituting with other manufacturers' equivalents.
