GALAXY ELECTRICAL
VOLTAGE RANGE: 30 V
CURRENT: 0.2 A
BAT85
SMALL SIGNAL SCHOTTKY DIODES
For general purpose applications
This diode 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
