Schottky Diode, 2 x 0.1 A
BAT54CW
Vishay High Power Products
FEATURES
• Small foot print, surface mountable
• Very low forward voltage drop
• Extremely fast switching speed for high frequency
operation
• Guard ring for enhanced ruggedness and long term
reliability
• Designed and qualified for industrial level
DESCRIPTION
This Schottky barrier diode is designed for high speed
switching applications, voltage clamping and circuit
protection. Miniature surface mount packages with reduced
foot print are excellent for portable applications where space
is limited.
