Low forward voltage drop of 0.6V at 1A. Commonly used for low-voltage power supply rectification and protecting against reverse battery connection.+A 1 A Schottky barrier rectifier in the axial DO-41 package, chosen wherever a low forward drop and fast recovery matter. Its forward voltage is only about 0.6 V at 1 A (versus ~1.1 V for a silicon 1N4007) and it switches almost instantly, so it wastes less power and works past line frequency. That makes it the default for switch-mode freewheeling, low-voltage rectification, reverse-polarity protection, and OR-ing supplies, at the cost of a higher reverse leakage than silicon. It blocks 40 V reverse; the banded end is the cathode (pin 1).++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | K | passive | Cathode terminal, identified by the cathode band on the package body.
