SCHOTTKY BARRIER DIODES
0.40 0.25
0.15 (max)
FEATURES :
* For general purpose applications * The SD103 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. * These diodes are also available in the MiniMELF case with type designations LL103A thru LL103C. * Pb / RoHS Free
MECHANICAL DATA :
* Case : SOD-323 plastic Case * Weight : approx. 0.004 g * SD103AWS Marking Code : S4 * SD103BWS Marking Code : S5 * SD103CWS Marking Code : S6
