Small Signal Schottky Diode
FEATURES
• For general purpose applications
• The LL101 series is a metal-on-silicon Schottky
barrier device which is protected by a PN
junction guard ring
• The low forward voltage drop and fast switching
make it ideal for protection of MOS devices,
steering, biasing and coupling diodes for fast switching
and low logic level applications
LINKS TO ADDITIONAL RESOURCES
• Integrated protection ring against static discharge
• Low capacitance
3D 3D
• Low leakage current
3D Models
• This diode is also available in the DO-35 (DO-204AH) case
