WSD751S
SMALL SIGNAL
SCHOTTKY DIODES
30m AMPERES
40 VOLTS
*Extrmely High Switching Speed.
*Low Forward Voltage and Low Reverse Current.
*High Reliability.
*Schottky Barrier Diodes Encapsulated in a SOD-523 Package
Description:
Feature:
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.
