Overview
The CDBA1150LR-HF is a Schottky barrier rectifier manufactured by Comchip Technology, housed in the DO-214AC (SMA) surface-mount package. It features a single diode configuration with a repetitive reverse voltage of 150 V and an average forward current of 1 A. The device exhibits a maximum forward voltage drop of 0.85 V at rated current and supports a peak forward surge current of 30 A. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Low forward voltage drop for high efficiency
- Ultra-fast switching capability
- High thermal resistance and power dissipation
- Guarding against overvoltage conditions
Applications
- DC-DC converters
- Power supply circuits
- Reverse polarity protection
Procurement Notes
Verify the specific suffix 'LR' against the official Comchip Technology datasheet to confirm lead-free status and RoHS compliance details. Ensure the DO-214AC package dimensions match your PCB footprint requirements. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component for applications requiring low forward voltage and high-speed rectification in a standard SMA package. Consider the 150 V reverse voltage rating and 1 A current capacity relative to circuit demands. Evaluate thermal management needs given the 150°C maximum operating temperature limit.
Part Context
This part belongs to Comchip Technology's discrete semiconductor portfolio, specifically their Schottky barrier rectifier line. The company specializes in SMD discrete semiconductors, including fast efficient rectifiers and switching diodes. The CDBA series utilizes flat chip manufacturing processes designed for reliability and performance in surface-mount applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative SMA-packaged Schottky diodes having equivalent 150 V and 1 A ratings through independent technical comparison.
