LL42/LL43
Small Signal Schottky Diodes
VOLTAGE : 30 V
MINI-MELF
Features
Cathode indification
◇
For general purpose applications
◇
These diodes feature 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.
