FEATURES
For general purpose applications
These diodes features very low turn-on voltage and fast switching.
These devices are protected by a PN junction guard ring against excessive
voltage, such as electrostatic discharges.
These diodes are also available in the MiniMELF case with type designation
LL42 to LL43.
