Leadless chip form factor for compact PCB layouts
Low forward voltage characteristics for improved efficiency
High current capability suitable for power applications

Applications

Switch Mode Power Supplies (SMPS)
Portable equipment batteries
DC/DC converters
Telecommunications
High frequency rectification

Procurement Notes

Verify the specific part number suffix against the manufacturer's datasheet to confirm electrical parameters. Ensure the component meets RoHS and halogen-free requirements for your manufacturing process. Confirm compatibility with standard surface-mount pick-and-place equipment during integration planning.

Selection Notes

Select this component for designs requiring a 1 A Schottky diode in an SOD-123 package. The 'L' designation indicates a low forward voltage variant compared to standard versions. Evaluate thermal resistance and derating curves for high-temperature environments to ensure reliable operation under load conditions.

Part Context

This component belongs to the CD123D-B1xR Schottky Barrier Chip Diode Series by Bourns Inc. The series provides small-signal Schottky diodes for switching and rectification in portable communications and computing equipment. The product line addresses market demands for miniaturization while maintaining robust electrical performance.

Replacement Considerations

Compatible substitutes include CD123D-B140R and CD123D-B120R from the same series. Verify that alternative parts match the required reverse voltage and forward current ratings before implementation.

FAQ

What is the difference between CD123D-B140R and CD123D-B140LR?

The primary difference is the forward voltage characteristic. The CD123D-B140LR is a low forward voltage variant, offering lower voltage drop compared to the standard CD123D-B140R.
