Schottky diode for low-voltage switching and rectification
The BAT54B5003 is a Schottky barrier diode from Infineon Technologies, housed in the standard SOT-23-3 surface-mount package (TO-236-3 / SC-59 / SOT-23-3). Schottky diodes offer fast switching and low forward voltage drop, making this part suitable for polarity protection, freewheeling, and high-speed rectification in power supplies and DC-DC converters where efficiency matters.
Supplied in Bulk packaging, the BAT54B5003 mounts via surface mount (SMT) and uses the PG-SOT23 supplier device package — a common footprint shared across the BAT54 family. The SOT-23-3 footprint is widely supported in reflow profiles and matches standard pad layouts for small-signal diodes, simplifying board integration without requiring a custom land pattern.
As a standard small-signal Schottky diode from Infineon, it is widely available through independent distribution; sourcing is confirmed per RFQ with pricing and lead time quoted at order time.
