Overview
The B5819WSL is a surface-mount Schottky barrier rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 1 A. The device utilizes a thin SOD-323 (SC-90) package, designed for low forward voltage drop applications. It operates within a junction temperature range of -55°C to +150°C and complies with RoHS standards.
Feature Summary
- Low forward voltage characteristic for improved efficiency
- Thin SMD package suitable for space-constrained designs
- High surge current capability
- Lead-free construction compliant with environmental directives
Applications
- General purpose rectification in consumer electronics
- Power supply input protection circuits
- DC-DC converter freewheeling diodes
- Polarity protection in portable devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package variant and tape-and-reel specifications. Ensure the component meets the required RoHS compliance status for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a compact surface-mount Schottky diode is required for low-voltage, high-current applications. The SOD-323 package offers a smaller footprint compared to standard axial or larger SMD packages. Consider the 40V reverse voltage rating and 1A current capacity relative to the circuit's peak operating conditions and thermal environment.
Part Context
This component belongs to the small signal Schottky diode category from SMC Diode Solutions. It is distinct from the SMBJ58CA TVS diode and ES1B fast recovery diode also listed in the source data. The B5819WSL is specifically engineered for low-loss rectification rather than transient suppression or high-speed switching.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers such as Micro Commercial Components (MCC), which produces the B5819WSL-TP, ensuring pinout and electrical parameters match exactly.
