CDLL485B

Single Diodes Overview

The CDLL485B is a hermetically sealed, metallurgically bonded switching diode manufactured by Microchip Technology. It features a double plug construction within the DO-213AA-2 (SOD-80) surface-mount package. The device supports a maximum DC reverse voltage of 180 V and an average rectified forward current of 200 mA. Key electrical parameters include a maximum reverse leakage current of 100 µA at 180 V and a maximum forward voltage of 1 V at 100 mA. It operates reliably across a temperature range of -65°C to +175°C.

Single Diodes Feature Summary

• Hermetically sealed construction with metallurgical bonding for enhanced reliability
• Double plug design suitable for high-reliability applications
• Surface-mount form factor in a compact DO-213AA-2 package

Single Diodes Applications

• High-reliability general-purpose rectification
• Switching circuits requiring hermetic sealing

Single Diodes Procurement Notes

Verify RoHS compliance status as historical data indicates non-compliance. Confirm package type availability and check for equivalent part numbers such as LL485B or CDLL485B if specific packaging variants are required. Ensure supplier documentation matches the exact Microchip Technology manufacturing specifications.

Single Diodes Selection Notes

Select this component when hermetic sealing and high-temperature operation up to 175°C are mandatory. The DO-213AA-2 package offers a compact solution for surface-mount designs. Consider the 180 V reverse voltage rating and 200 mA current capacity against circuit requirements. Verify that the metallurgical bond construction meets the specific reliability standards of the target application.

Single Diodes Part Context

This part belongs to the Microchip Technology diode family, specifically designed for robust performance. It shares functional similarities with the LL485B and CDLL485B variants, differing primarily in packaging or minor specification tolerances. The device is categorized under standard switching diodes intended for demanding industrial or aerospace environments.

Single Diodes Replacement Considerations

Officially documented substitutes include LL485B and CDLL485B. Verify pinout compatibility and ensure the replacement maintains the hermetic seal requirement if applicable.
