FEATURES
For general purpose applications.
♦
♦
The SD103 series is a metal-on-silicon
Schottky barrier de vice which is pr otected
by a PN junct ion guard ring. The lo w f or ward
voltage drop an d f ast switching make it id ea l for
protection of MOS devices, steering, biasing, and
coupling diodes f or f ast s witchi ng and lo w logic le vel
applications. Other applicat i ons are click suppression,
efficient full wa ve bridges in
telephone subsets, and blocking diodes in
rechargeabl e lo w voltage battery systems.
♦
This diode is also avai l able in MiniMELF case with the
type designation LL103A … LL103C and SOD-123 c ase
with the type designations SD103AW .. SD103CW.
