SD101A - SD101C SCHOTTKY BARRIER DIODES
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.
with type designations LL101A thru LL101C.
• Pb / RoHS Free
