Single Diodes datasheet and documents for BAT54FSTR
Single Diodes Overview
The BAT54FSTR is a surface-mount Schottky barrier diode manufactured by onsemi, housed in an SOT-23 (TO-236AB) plastic package. It features a dual-diode configuration with a common cathode arrangement. The device is rated for a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 200 mA. Key electrical characteristics include a low forward voltage drop of approximately 1 V at 100 mA and a maximum reverse leakage current of 25 µA at the rated voltage.
Single Diodes Feature Summary
- Low forward voltage drop for efficient signal processing
- Guard ring protected structure for enhanced reliability
- Common cathode dual-diode configuration
Single Diodes Applications
- Ultra high-speed switching circuits
- Voltage clamping applications
- Protection circuits for sensitive components
- Blocking diodes in power paths
Single Diodes Procurement Notes
Verify the specific suffix 'FSTR' against the official onsemi datasheet to confirm tape-and-reel packaging specifications and marking codes. Ensure the component matches the standard BAT54 electrical parameters. Confirm RoHS compliance status as per the manufacturer's latest material declaration before integration into production.
Single Diodes Selection Notes
Select this component when a low-capacitance, fast-switching Schottky diode is required in a compact SOT-23 footprint. The common cathode configuration simplifies circuit design for dual-channel protection or logic isolation. Verify that the 30 V reverse voltage rating meets the system's peak inverse voltage requirements.
Single Diodes Part Context
This part belongs to the BAT54 family of Schottky barrier diodes from onsemi. The family includes variants such as BAT54A, BAT54C, and BAT54S, which differ primarily in internal pinning configurations and forward voltage characteristics. All share the same small outline transistor package and general performance profile.
Single Diodes Replacement Considerations
Compatible substitutes include BAT54ST/R from NXP and BAT54S-TR from Vishay. These alternatives offer similar electrical ratings and pinouts but require verification of the specific suffix markings and packaging details to ensure mechanical compatibility.
