BAT48 SCHOTTKY BARRIER DIODE
FEATURES :
• 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 case
with type designations LL48
• Pb / RoHS Free
