CDBMTS1200-HF

Overview

The CDBMTS1200-HF is a low-profile Schottky barrier rectifier manufactured by Comchip Technology. It features a silicon epitaxial planar chip with a metal-silicon junction, housed in an SOD-123F-2 package that is 40% thinner than standard SOD-123 devices. Key electrical parameters include a forward current of 1 A, a repetitive reverse voltage of 200 V, and a maximum forward voltage drop of 0.92 V at rated conditions. The device supports a forward surge current of 30 A and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Low profile package design reduces physical footprint compared to standard SOD-123 components
• Ultra high-speed switching capability for efficient power conversion
• Excellent power dissipation providing improved thermal resistance and lower reverse leakage current
• Guarding functionality for overvoltage protection scenarios

Applications

• High efficiency DC/DC converters
• Power factor correction circuits
• Free-wheeling diodes in synchronous rectification designs
• Overvoltage protection stages in sensitive electronic loads

Procurement Notes

Verify the specific suffix against official Comchip Technology documentation to confirm exact electrical tolerances and packaging configurations. Ensure the component meets required environmental standards such as MIL-STD-19500/228 if applicable to your system. Cross-reference the datasheet version date to ensure alignment with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a low-profile surface mount solution without sacrificing current handling capabilities. The 200 V rating makes it suitable for intermediate bus voltage applications. Consider the thermal resistance benefits of the specialized package for high-density PCB layouts where heat dissipation is critical for long-term reliability.

Part Context

This part belongs to the CDBMT Series of low-profile Schottky barrier rectifiers from Comchip Technology. The series is engineered to offer superior power dissipation and thermal performance compared to traditional equivalents. The CDBMTS1200-HF specifically targets applications requiring robust surge capability and fast switching speeds in a compact form factor.

Replacement Considerations

Direct substitutes must match the SOD-123F-2 package, 1 A forward current, and 200 V reverse voltage ratings. Verify that alternative Schottky diodes maintain comparable forward voltage drops and thermal resistance characteristics to ensure circuit performance parity.
