Overview
The CDBB1100-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration in an SMB (DO-214AA) package. Key electrical parameters include a repetitive reverse voltage (Vrrm) of 100 V and a forward current (If) of 1 A. The device exhibits a maximum forward voltage (Vf) of 0.85 V at rated current and supports a forward surge current (Ifsm) of 30 A. It operates within a temperature range of -55°C to +150°C junction temperature.
Feature Summary
- Low forward voltage drop for improved efficiency
- High thermal stability with extended operating temperature range
- Halogen-free construction compliant with environmental standards
Applications
- DC-DC converter output rectification
- Power supply freewheeling diodes
- Reverse polarity protection circuits
Procurement Notes
Verify the specific ordering suffix to ensure compliance with required environmental regulations, such as halogen-free status. Confirm that the DO-214AA package dimensions match your PCB footprint requirements. Check for any recent product change notifications or lifecycle status updates from Comchip Technology prior to finalizing procurement plans.
Selection Notes
Select this component when a low-loss rectification solution is needed in a compact SMB package. Ensure the circuit's peak inverse voltage does not exceed 100 V and the average forward current remains within 1 A limits. Consider the thermal management capabilities of the design given the high junction temperature rating.
Part Context
This part belongs to Comchip Technology's CDBB series of low-profile Schottky barrier rectifiers. These devices are engineered for general-purpose power conversion applications requiring fast switching speeds and low reverse recovery charge. The series offers various voltage ratings while maintaining consistent current handling capabilities across different package types.
Replacement Considerations
Direct substitutes may include other 1A 100V Schottky diodes in the DO-214AA package, such as those from Vishay or Diodes Inc., provided pinout compatibility and electrical specifications align.
