Schottky barrier (double) diodes
BAS40 series
FEATURES
Low forward voltage
Guard ring protected
Small plastic SMD package
Low diode capacitance.
APPLICATIONS
Ultra high-speed switching
Voltage clamping
Protection circuits
Blocking diodes.
DESCRIPTION
Planar Schottky barrier diodes with an
integrated guard ring for stress
protection. Single diodes and double
diodes with different pinning are
available. The diodes BAS40,
BAS40-04, BAS40-05 and BAS40-06
are encapsulated in a SOT23 small
plastic SMD package. The BAS40-07
is encapsulated in a SOT143B small
plastic SMD package
