Overview
The CDBAT1100-HF is a surface-mount Schottky barrier rectifier from Comchip Technology, rated for an average forward current of 1.0 A and a repetitive peak reverse voltage of 100 V. It utilizes a leadless 2010 package with FRP substrate and epoxy underfill. Key electrical characteristics include a maximum reverse leakage current of 0.47 mA at 25°C and a junction-to-ambient thermal resistance of 88 °C/W. The device supports an operating junction temperature range of -55 to +150°C and features pure tin plated terminals compliant with MIL-STD-750.
Feature Summary
- Leadless chip form factor designed to prevent lead damage during assembly.
- Low power loss and high efficiency due to low forward voltage drop.
- High surge current capability suitable for transient protection applications.
Applications
- General purpose rectification in surface mount circuits
- Power supply input/output stages
- Protection against reverse polarity
Procurement Notes
Verify the specific datasheet revision (Rev B) matches your design requirements. Confirm that the 2010 package dimensions align with your PCB footprint layout. Ensure compliance with RoHS and Halogen-free standards if required by your manufacturing process. Check terminal solderability specifications against your reflow profile.
Selection Notes
Select this component when a compact 2010 footprint is necessary for high-current rectification. Compare the 100V rating against circuit peak inverse voltages. Evaluate the 88 °C/W thermal resistance for heat dissipation needs. Consider the 1.0A continuous current limit for steady-state operation loads.
Part Context
This part belongs to the CDBAT series of SMD Schottky Barrier Rectifiers manufactured by Comchip Technology. The series includes variants with reverse voltages ranging from 20V to 100V, all sharing the same 1.0A forward current rating and 2010 package style. The CDBAT1100-HF represents the highest voltage option within this specific low-profile family.
Replacement Considerations
Direct substitutes must match the 100V reverse voltage, 1.0A forward current, and 2010 package outline. Verify thermal resistance and forward voltage characteristics for equivalent performance. Cross-reference with other manufacturers offering identical pinout and mechanical dimensions for the 2010 case type.
