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
