The CD1408-R1200 is a surface mount rectifier diode designed for high-frequency switching applications in compact portable electronics. This glass passivated device features a maximum repetitive peak reverse voltage (VRRM) of 200 V, maximum RMS voltage of 140 V, and a maximum average forward rectified current of 1.0 A, with a forward voltage drop of 1.0 V at rated current. The diode exhibits low reverse leakage current (1.0 µA at 25 °C, 30 µA at 125 °C) and a maximum reverse recovery time of 3000 ns, making it suitable for efficient rectification with minimal power loss. Operating across a temperature range of -65 °C to +175 °C, the device is packaged in a low-profile 1408 chip format (approximately 0.14 × 0.08 inches) compatible with SOD87 and SOD123 footprints, offering significant PCB real estate savings. Common applications include high-frequency switching power supplies, inverters, free-wheeling circuits, and polarity protection in portable communications, computing, and video equipment.
