Planar Schottky barrier diode  BAT54S  encapsulated in a SOT23 small plastic SMD package. Single diodes and double diodes with different pinning are available.


The Schottky barrier diode BAT54S is designed for high speed switching applications, circuit protection, and voltage clamping. Extremely low forward voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and portable applications where space is limited.
