BAT54WS

Single Diodes Overview

The BAT54WS is a surface mount Schottky barrier diode manufactured by SMC Diode Solutions. It features a single diode configuration in an SOT-23 package. Key electrical parameters include a maximum repetitive reverse voltage of 30 V and a continuous forward current of 200 mA. The device exhibits a low forward voltage drop of 800 mV at 100 mA and a peak non-repetitive forward surge current of 600 mA. Operating temperatures range from -55°C to +150°C, with a power dissipation rating of 200 mW.

Single Diodes Feature Summary

• Schottky barrier construction for ultra-fast switching and low reverse recovery time
• Plastic encapsulate compliant with UL94V-0 flammability ratings
• Designed for surface mount applications with polarity band marking

Single Diodes Applications

• Automotive electronics systems
• General purpose rectification
• Clamping and protection circuits

Single Diodes Procurement Notes

Verify the manufacturer designation on the component marking code, as SMC Diode Solutions may utilize specific lot traceability codes distinct from other producers. Confirm RoHS compliance status through the official datasheet revision history or supplier certification documents prior to integration into regulated assemblies.

Single Diodes Selection Notes

Select this component when a single Schottky diode in an SOT-23 package is required for high-speed switching applications. Ensure the 30 V reverse voltage rating exceeds the circuit's peak inverse voltage. Verify that the 200 mA average forward current meets the load requirements and that the thermal management strategy supports the 200 mW power dissipation limit.

Single Diodes Part Context

This part belongs to the BAT54 series of small signal Schottky diodes. These devices are widely used in consumer and automotive electronics due to their compact SOT-23 footprint and fast switching characteristics. The series typically includes variants with different internal configurations, such as dual diodes or common cathode arrangements, but the BAT54WS specifically denotes a single diode unit.

Single Diodes Replacement Considerations

Cross-reference with BAT54WS from Diodes Incorporated or Nexperia. Verify pinout compatibility and electrical parameter equivalence before substitution.
