LL85
SMALL SIGNAL SCHOTTKY DIODES
FEATURES
For general purpose applications
Mini-MELF
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.
This diode is also available in the DO-35 glass case
with type designation LL85.in the Micro-MELF case
with type designation MCL85
