Overview
The B245AE-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated, housed in the SMA (DO-214AC) surface-mount package. It features a maximum repetitive peak reverse voltage of 45V and an average forward rectified current of 2.0A. The device exhibits a low forward voltage drop of 0.50V maximum at 2A and a very low reverse leakage current of 0.2mA maximum at rated DC blocking voltage. Designed for high-efficiency power conversion, it operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Schottky barrier construction for ultra-fast recovery and minimal heat generation
- Low forward voltage drop to enhance overall system efficiency
- High surge current capability for robust transient protection
- Molded plastic package utilizes UL recognized flame retardant materials
Applications
- DC-to-DC converters
- Power supply circuits
- Adapters
- Polarity protection applications
Procurement Notes
Verify the specific suffix 'AE' against the official Diodes Incorporated datasheet to confirm the SMA package variant and electrical ratings. Ensure the component meets RoHS compliance requirements if mandated by your design specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a compact surface-mount solution is required for low-voltage, high-current rectification. The 45V rating suits 5V and 12V systems, while the 2.0A current capacity supports moderate power loads. Consider the thermal performance and package size relative to PCB space constraints and ambient operating temperatures during circuit design.
Part Context
This component belongs to the B245 series of Schottky rectifiers from Diodes Incorporated. The series offers various voltage and current combinations in standard packages like SMA and SMB. The B245AE-13 specifically targets applications needing reliable rectification in a small footprint, leveraging the company's semiconductor manufacturing expertise for consistent quality and performance.
Replacement Considerations
Compatible substitutes include the B245AF-13 or generic equivalents such as SS24 or SS26 from other manufacturers, provided they match the 45V/2A SMA specification. Verify pinout compatibility and thermal characteristics before substitution.
