Description

RF2001NS3D is Super Fast Recovery Diode. A 350V, 20A Super Fast Recovery Diode is an electronic component designed to handle high voltage and high current levels while having fast recovery times. These diodes are commonly used in power electronic circuits, switching power supplies, and rectification applications where low switching losses and high-speed switching capabilities are essential.

Super Fast Recovery Diodes are specifically designed to minimize the reverse recovery time (trr) and reverse recovery charge (Qrr) compared to standard diodes. This reduces the diode’s turn-off losses and makes it suitable for high-frequency switching applications where fast switching times are critical to achieve high efficiency and minimize heat dissipation.
