GALAXY ELECTRICAL
VOLTAGE : 40 V
BAT48
SMALL SIGNAL SCHOTTKY DIODE
◇
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.
◇
This diode is also available in the Mini-MELF
DO - 35
