CD214A-F1400 is a glass passivated fast response rectifier diode designed for rectification applications in portable communications, computing, and video equipment. The device features a maximum repetitive peak reverse voltage (VRRM) of 400V, maximum RMS voltage of 280V, and a maximum average forward rectified current of 1.0A, with low reverse leakage current and low forward voltage drop. It is housed in a compact DO-214AC (SMA) surface mount package with dimensions of 4.83–5.59 mm length and 2.29–2.92 mm width, offering significant PCB real estate savings compared to larger packages. The diode exhibits a maximum instantaneous forward voltage of 1.25V at 1A and a typical reverse recovery time of 30ns, making it suitable for high-speed switching applications. Common applications include power supply rectification, signal detection, and protection circuits in consumer electronics and industrial equipment.
