Overview
The B5817WS-TP is a single-element silicon Schottky barrier rectifier manufactured by Micro Commercial Components. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes an SOD-323 surface-mount package, specifically the PLASTIC PACKAGE-2 form factor. Key electrical characteristics include a low forward voltage drop and high surge current capability. The component operates within a junction temperature range of -65°C to +150°C and offers guard ring protection for enhanced reliability in low-voltage, high-frequency applications.
Feature Summary
- Guard ring protection structure for improved stability
- Low forward voltage drop for high efficiency
- High surge current capability for robust operation
- Suitable for low voltage, high frequency inverters
Applications
- Low voltage power supplies
- High frequency inverters
- Free-wheeling diodes
- Polarity protection circuits
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest datasheet to confirm exact electrical tolerances and packaging variations. Ensure the ordering part number matches the required voltage rating and package type. Cross-reference with official Micro Commercial Components documentation to validate RoHS compliance status and any recent product change notifications before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring a compact surface-mount Schottky rectifier with 1 A continuous current handling. The 20 V reverse voltage rating suits low-voltage DC systems. Consider the SOD-323 footprint constraints and thermal dissipation requirements. Verify that the operating environment stays within the specified temperature range and that the low forward voltage characteristic aligns with system efficiency goals.
Part Context
This part belongs to the B5817WS series of 1 Amp Schottky Barrier Rectifiers from Micro Commercial Components. The series includes variants with different reverse voltage ratings, such as 30 V and 40 V options. These devices are designed for general-purpose rectification in space-constrained surface-mount applications, offering a balance of performance and reliability in small plastic packages.
Replacement Considerations
Direct substitutes may include other 1 A, 20 V Schottky rectifiers in the SOD-323 package. Verify pinout compatibility and thermal resistance values. Alternative parts must meet or exceed the 1 A forward current and 20 V reverse voltage specifications. Check for equivalent forward voltage drop and reverse leakage current characteristics to ensure circuit performance parity.
