CDLL255/TR

Current Regulation - Diodes, Transistors Overview

The CDLL255/TR is a temperature-compensated Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.2 V with a tolerance of 10%. The device operates in the SMD/SMT configuration within a DO-213AA-2 (PD) package, supporting a maximum power dissipation of 500 mW. Electrical characteristics include a maximum reverse leakage current of 2 µA and a Zener impedance of 10 Ω at a test current of 7.5 mA. The component is rated for an operating temperature range from -65 °C to +175 °C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the requested part number matches the exact electrical tolerances and temperature ratings required for the target application before finalizing procurement orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 6.2 V reference is needed under significant thermal stress. Compare the 10 Ω impedance and 2 µA leakage against circuit requirements. Verify that the DO-213AA-2 footprint aligns with the PCB layout constraints and that the 500 mW power rating accommodates the expected dissipation levels.

Current Regulation - Diodes, Transistors Part Context

This part belongs to Microchip's CDLL series of axial-leaded style surface-mount Zener diodes. These components are designed for reliability in demanding electronic systems where standard Zener diodes might drift due to temperature changes. The 'TR' suffix typically indicates reel packaging for automated assembly processes.

Current Regulation - Diodes, Transistors Replacement Considerations

Consult Microchip's official cross-reference documentation or equivalent manufacturer datasheets for direct pin-compatible substitutes. Verify that any alternative maintains the 6.2 V nominal voltage, 10% tolerance, and DO-213AA-2 package dimensions to ensure mechanical and electrical compatibility.
