The 1N5819 Microdiode Electronics SBD with DO-41 RoHS is a rectifier diode in a DO-41 (JEDEC TO-204AA) package. It incorporates a Schottky barrier diode with an integrated guardring construction to protect the diode from excessive current. It has a reverse blocking voltage of up to 30V and a forward voltage of only 0.41V at 1A of current. Its maximum power dissipation is one watt, and its average rectified current is 1A. The 1N5819 provides a low-cost, fast, and reliable solution for high-efficiency operations. In addition, it is RoHS (Restriction of Hazardous Substances) compliant, meaning it does not contain any hazardous substances which can cause environmental or health issues.
