Overview
The CDBA1100LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface mount applications in the DO-214AC (SMA) package. It features a single diode configuration with silicon epitaxial planar technology. Key electrical parameters include a repetitive reverse voltage (Vrrm) of 100 V and an average forward current (If) of 1 A. The device exhibits a maximum forward voltage drop (Vf) of 0.85 V at rated current and a reverse leakage current (Ir) of 0.5 mA. It supports a forward surge current (Ifsm) of 30 A and operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Ultra-high-speed switching capability for efficient power conversion
- Low forward voltage drop reduces power loss and increases efficiency
- Guarding against overvoltage transients due to high surge capability
- Lead-free construction compliant with environmental standards
Applications
- High-frequency DC-DC converters
- Power supply freewheeling diodes
- Overvoltage protection circuits
- Polarity protection in low-voltage systems
Procurement Notes
Verify the specific ordering suffix and RoHS status directly with the manufacturer or authorized distributors, as compliance statuses may be in transition. Confirm that the DO-214AC package dimensions match your PCB footprint requirements. Ensure the selected component meets the thermal management needs of your final assembly, given the 150°C maximum operating temperature rating.
Selection Notes
Select this component when a 100 V reverse voltage rating and 1 A continuous current are required in a compact SMA package. It is suitable for designs prioritizing low forward voltage drop to minimize conduction losses. Consider the 0.5 mA reverse leakage current specification for sensitive circuitry. The SMD mounting style facilitates automated assembly processes.
Part Context
This part belongs to Comchip Technology's CDBA series of low-profile Schottky barrier rectifiers. The series is characterized by silicon epitaxial planar chips and metal-silicon junctions. These devices are engineered to offer excellent power dissipation and better thermal resistance compared to standard counterparts, supporting high-efficiency applications in modern electronics.
Replacement Considerations
Direct substitutes must match the 100 V, 1 A, SMA package specifications. Verify equivalent Vf and Ir characteristics to ensure performance parity. Cross-reference with other manufacturers offering SMA Schottky diodes with similar surge current ratings and operating temperature ranges.
