Product specification
Schottky barrier (double) diodes
BAS70 series
FEATURES
Low forward current
High breakdown voltage
Guard ring protected
Small plastic SMD package
Low diode capacitance.
APPLICATIONS
Ultra high-speed switching
Voltage clamping
Protection circuits.
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 BAS70, BAS70-04,
BAS70-05 and BAS70-06 are
encapsulated in a SOT23 small
plastic SMD package. The BAS70-07
is encapsulated in a SOT143B small
plastic SMD package.
