LL103A - LL103C SCHOTTKY BARRIER DIODES
FEATURES :
• For general purpose applications
• The LL103A, B, C 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.
full wave bridges in telephone subsets, and
blocking diodes in rechargeable low voltage
battery systems.
• These diodes are also available in the DO-35 case with
type designation SD103A, B, C
• Pb / RoHS Free
