The 1N5819 with Schottky Barrier Diodes (SBD) DO-41 RoHS manufactured by DIOFIT is a type of semiconductor device made from a thin layer of metal deposited between a semiconductor Junction. Due to the barrier in the junction, this type of diode exhibits a low forward voltage drop and therefore a much smaller power loss than a normal diode, providing higher efficiency. It is used to protect circuits from overvoltage surges, and it also helps to reduce power dissipation in the circuit. It is typically used in high frequency switching applications such as DC-DC converters, switching power supplies, and motor controls. It can handle both rectified and switching applications with a reverse voltage of up to 20 V and forward current of up to 1A. The diode has a RoHS compliant finish and is available in DO-41 packages.
