Overview
The CD123D-B120R is a Schottky Barrier Chip Diode from Bourns, packaged in the SOD-123 size format. It features a maximum repetitive peak reverse voltage of 20 V and supports a maximum average forward rectified current of 1 A at an ambient temperature of 55 °C. The device exhibits a typical instantaneous forward voltage of 0.46 V at 1.0 A and a junction capacitance of 110 pF at 4 V reverse bias. It operates within a junction temperature range of -55 to +125 °C and can withstand a peak forward surge current of 20 A.
Feature Summary
- RoHS compliant and halogen-free construction
- Leadless chip form factor for compact PCB layouts
- High current capability with low forward voltage drop
Applications
- Switch Mode Power Supplies (SMPS)
- Portable equipment batteries
- High frequency rectification
- DC/DC converters
- Telecommunications
Procurement Notes
Verify component authenticity by checking markings against official datasheet codes. Confirm RoHS compliance status and halogen-free specifications match project requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines. Validate thermal performance under actual operating loads before final integration.
Selection Notes
Select this model for applications requiring a 20 V reverse voltage rating and 1 A continuous forward current. The SOD-123 package suits space-constrained designs needing standard surface mount compatibility. Consider the specific forward voltage characteristics for efficiency calculations in low-voltage power paths.
Part Context
This component belongs to the CD123D-B1xR Schottky Barrier Chip Diode Series. It is designed for portable communications, computing, and video equipment where miniaturization is critical. The series offers options for different reverse voltages and forward voltage profiles within the same physical footprint.
Replacement Considerations
Compatible substitutes include CD123D-B140R and CD123D-B140LR from the same series, provided the higher 40 V reverse voltage rating does not conflict with circuit design constraints.
