ROHM RB421DT146 Schottky Barrier Diode

The RB421D is a Schottky barrier diode designed for small current rectification applications, providing high reliability with a compact SOT-346 package. It features a maximum reverse voltage of 40V, average forward current of 100mA, and low forward voltage drop, ideal for power circuits requiring efficient, fast switching. Its epoxy resin package ensures durability, and it is suitable for use in embedded systems, small power supplies, and rectification setups. The diode's low capacitance of 6pF at 10V makes it suitable for high-frequency applications while maintaining stability and fast response times.
