Overview
The CDBMT140-HF is a low-profile Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration with a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage rating of 40 V. The device exhibits a typical forward voltage drop of 0.5 V at rated current. It supports a forward surge current of 25 A and operates within a junction temperature range of -55°C to +125°C.
Feature Summary
- Utilizes majority carrier conduction for high switching efficiency
- Features a low-profile surface-mount package design
- Constructed with silicon technology for robust performance
Applications
- High-frequency rectification in power supply circuits
- DC-DC converter output stages
- Free-wheeling diodes in inductive load protection
Procurement Notes
Verify the specific datasheet version and RoHS compliance status prior to procurement, as manufacturing transitions may affect certification details. Confirm that the ordering suffix corresponds exactly to the required packaging format, such as cut tape or reel, to ensure compatibility with automated assembly equipment. Cross-reference the manufacturer's part number against official distributor catalogs to validate authenticity and traceability.
Selection Notes
Select this component when a compact form factor is required alongside moderate current handling capabilities. Ensure the circuit's peak inverse voltage does not exceed the 40 V rating under all operating conditions. Consider the thermal management requirements given the 125°C maximum junction temperature limit and the specific forward voltage characteristics at the expected load current.
Part Context
This device belongs to the CDBMTxxx series of low-profile Schottky barrier rectifiers from Comchip Technology. The series offers various voltage ratings including 60 V, 100 V, and 150 V options for both 1 A and 2 A current variants. These components are designed for surface-mount applications requiring efficient rectification in space-constrained electronic designs.
Replacement Considerations
Consult official substitution guides for equivalent Schottky rectifiers with matching 1 A current and 40 V voltage ratings. Verify pinout compatibility and package dimensions before integrating alternative parts into existing layouts.
