Vishay Semiconductors
Small Signal Schottky Diode
FEATURES
• For general purpose applications
• This diode features very low turn-on voltage and
fast switching. This device is protected by a PN
junction guard ring against excessive voltage,
such as electrostatic discharges
• This diode is also available in the SOD-123 case
with type designation BAT46W-V and in the
MiniMELF case with type designations LL46
• AEC-Q101 qualified
• Material categorization: For definitions of compliance
