Single Diodes Procurement Notes

Verify the specific datasheet version for the BAT54-HF to confirm exact electrical tolerances and thermal resistance values. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, as availability may vary by distributor. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a dual Schottky diode with common cathode topology is required in a small SOT-23-3 footprint. It is appropriate for designs prioritizing low forward voltage and rapid switching over ultra-low leakage current. Compare the 200 mA continuous current rating against the application's peak load requirements to ensure adequate headroom.

Single Diodes Part Context

This part belongs to the BAT54 series of Schottky barrier rectifiers produced by Comchip Technology. The series is characterized by silicon construction and surface-mount compatibility. Variants within the family, such as BAT54A and BAT54C, differ primarily in internal configuration and forward voltage characteristics while sharing similar package constraints.

Single Diodes Replacement Considerations

Compatible substitutes include BAT54A-G and BAT54C-G from Comchip Technology. Verify that alternative parts match the SOT-23-3 package dimensions and pinout assignments. Ensure the replacement maintains the required 30 V reverse voltage rating and sufficient current handling capacity for the specific circuit application.
