## Dual Series Schottky Barrier Diodes
## **30 VOLT DUAL COMMON CATHODE SCHOTTKY BARRIER DIODES**
## BAT54CW
These Schottky barrier diodes are 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.
