The CDI 1N5819-1 and 1N6761-1 are 100V, 1A, ultra-fast switching diodes in the DO-41 package. They are ideal for switching applications such as motor control, power supplies, and inverters.
This datasheet presents CDI's hermetically sealed Schottky barrier rectifiers, including the 1N5819, DSB5817, DSB5818, the 1N6759‑1N6761 series, and the DSB1A20‑DSB1A100 series. The devices feature copper‑clad steel leads with a tin/lead finish and are designed for a wide temperature range.
Key specifications include operating temperatures from –55 °C to +125 °C, storage temperatures down to –55 °C, a maximum average forward current of 1 A at +55 °C, and detailed reverse voltage and forward voltage data for each part number. The diodes are rated for various reverse voltages (e.g., 40 V for 1N5819) and exhibit low forward voltage drops, making them suitable for high‑efficiency power applications.
