Overview
The CDBMH3100-HF is a Schottky Barrier Rectifier manufactured by Comchip Technology, housed in an SOD-123T (Mini-SMA) surface-mount package. It features a repetitive peak reverse voltage of 100 V and a continuous forward current rating of 3.0 A. The maximum forward voltage at 3.0 A is 0.85 V, with a typical thermal resistance of 56 °C/W. The device supports a maximum forward surge current of 80 A for an 8.3 ms half-sine wave. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Ultra high-speed switching capability utilizing silicon epitaxial planar chip technology.
- Low profile surface mount design optimized for board space efficiency.
- High surge capability combined with low power loss and high efficiency.
- Guarding functionality designed for overvoltage protection applications.
Applications
- Overvoltage protection circuits
- Space-constrained surface mount assemblies
- High-efficiency rectification systems
Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical ratings and physical dimensions. Ensure compliance with environmental standards such as MIL-STD-19500/228 for lead-free requirements. Cross-reference datasheet specifications for thermal resistance and junction capacitance prior to integration into final designs.
Selection Notes
Select this component when a 100 V reverse voltage rating and 3.0 A continuous current are required in a compact SOD-123T footprint. Consider the 0.85 V forward voltage drop for efficiency calculations. Evaluate the 56 °C/W thermal resistance for heat dissipation needs within the specified operating temperature range.
Part Context
This device belongs to the CDBMH series of SMD Schottky Barrier Rectifiers produced by Comchip Technology. The series utilizes a molded plastic case with solderable terminals. The product line emphasizes batch process design for consistent power dissipation and reverse leakage current performance across the family.
Replacement Considerations
Compatible substitutes include other SOD-123T packaged Schottky diodes rated for 100 V and 3.0 A. Verify pinout alignment (cathode on Pin 1) and ensure equivalent forward voltage and surge current capabilities before substitution.
FAQ
What is the maximum non-repetitive forward surge current?
The maximum forward surge current is 80 A for an 8.3 ms single half-sine wave superimposed on rated load.
How is polarity indicated on the component?
Polarity is indicated by the cathode band located on one end of the device body.
