Vishay SD103ATR Small Signal Schottky Diode

The SD103A-TR is a small signal Schottky diode featuring a low forward voltage drop and fast switching capabilities. It is ideal for protecting MOS devices, as well as for steering, biasing, and coupling in fast switching and low logic level applications. Crafted with a metal-on-silicon Schottky barrier and protected by a PN junction guard ring, this diode is suitable for general-purpose use. Applications include click suppression, efficient full-wave bridges in telephone systems, blocking diodes in low-voltage rechargeable battery systems, high-frequency detection, protection circuits, small battery chargers, and AC/DC/DC-DC converters. Additionally, it is AEC-Q101 qualified and designed to operate at a junction temperature of 125°C.
