LRC LBAT54ALT1G Schottky barrier diode Datasheet

LESHAN RADIO COMPANY, LTD.
Schottky Barrier Diodes
These Schottky barrier diodes are designed for high speed switching applications, circuit protection, and voltage clamping. Extremely
LBAT54ALT1
low forward voltage reduces conduction loss. Miniature surface mount
package is excellent for hand held and portable applications where
space is limited.
