Overview
The CDBF0140L-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a peak repetitive reverse voltage of 40V and an average forward rectified current of 1A. The device utilizes a low-profile TO-269AA (SMA) surface-mount package. Key electrical parameters include a maximum DC blocking voltage of 40V, a forward current rating of 1A, and a non-repetitive peak forward surge current capability. The component operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Low forward voltage drop for high efficiency
- Ultra-fast switching characteristics
- High surge current capability
- Lead-free construction compliant with environmental standards
Applications
- DC-DC converters
- Power supplies
- Adapters
- Free-wheeling diodes in inductive circuits
Procurement Notes
Verify the specific suffix 'HF' confirms halogen-free status as per manufacturer documentation. Confirm the TO-269AA package dimensions match PCB footprint requirements. Ensure the 40V reverse voltage rating exceeds the circuit's peak inverse voltage. Check RoHS compliance declarations against current regulatory updates.
Selection Notes
Select this component when a 1A Schottky rectifier is required in a compact SMA-style package. The 40V rating suits low-voltage power rails. Consider the 175°C junction temperature limit for high-thermal environments. Compare forward voltage specifications against alternative brands for efficiency optimization.
Part Context
This part belongs to Comchip Technology's low-profile Schottky rectifier series. These devices are designed for space-constrained applications requiring high reliability. The series emphasizes thermal performance and low leakage current. They serve as alternatives to standard silicon rectifiers in high-frequency switching applications.
Replacement Considerations
Cross-reference with other 1A 40V Schottky diodes in TO-269AA packages. Verify pinout compatibility before substitution. Ensure equivalent forward voltage and reverse leakage specifications.
