Overview
The B5817WS is a single-element silicon Schottky barrier rectifier manufactured by Micro Commercial Components (MCC). It features a maximum repetitive peak reverse voltage of 20 V and an average forward current rating of 1 A. The device utilizes a SOD-323 surface-mount plastic package with two terminals. Key electrical characteristics include low forward voltage drop and high surge current capability, making it suitable for low-voltage, high-frequency inverter applications.
Feature Summary
- Guard ring protection structure
- Low forward voltage drop
- High surge current capability
Applications
- Low voltage inverters
- High frequency inverters
- Free wheeling circuits
- Polarity protection applications
Procurement Notes
Verify the manufacturer designation as Micro Commercial Components (MCC) when sourcing this component. Confirm the specific suffix 'WS' corresponds to the SOD-323 package type. Ensure compliance with RoHS directives if required by your application standards. Cross-reference datasheet parameters such as thermal resistance and operating temperature range against your system requirements before finalizing procurement decisions.
Selection Notes
Select the B5817WS for designs requiring a compact surface-mount Schottky rectifier with a 20 V reverse voltage rating. Its small outline package facilitates automated assembly processes. Consider its low forward voltage characteristics for efficiency optimization in low-voltage power conversion stages. Evaluate the thermal performance within the specified junction-to-ambient resistance limits during circuit design.
Part Context
This component belongs to the B5817WS through B5819WS series of 1 Amp Schottky Barrier Rectifiers. The series offers varying reverse voltage ratings from 20 V to 40 V while maintaining consistent current handling capabilities. These devices are designed for general-purpose rectification in space-constrained electronic assemblies requiring reliable switching performance.
Replacement Considerations
Compatible substitutes within the same MCC series include B5818WS and B5819WS, which share identical physical packages and current ratings but offer higher reverse voltage tolerances of 30 V and 40 V respectively. Verify pinout compatibility and thermal characteristics when substituting.
