The RB491DT146 is a Schottky barrier diode designed for low-voltage, high-speed rectification applications. It offers a maximum reverse voltage of 20V and can handle an average rectified current of 1A. The forward voltage is typically 450mV at 1A forward current, enabling efficient operation with minimal power loss.
The diode is characterized by fast recovery speed (≤500ns, >200mA), making it suitable for switching power supplies and other high-frequency circuits. It operates over a junction temperature range up to 125°C.
The device is supplied in a surface-mount SMD3 package, which is compatible with TO-236-3, SC-59, and SOT-23-3 footprints. This compact package is ideal for space-constrained designs.
