CDSUR400B

The CDSUR400B is a switching diode manufactured by Comchip Technology, designed for surface-mount applications. It is housed in a 0603/SOD-523F package, which is extremely thin and leadless, making it suitable for high-density PCB designs. The diode has a maximum average rectified current of 100 mA and a reverse voltage rating of 80V. It features a fast reverse recovery time of 4 ns (max) under test conditions of VR=6V, IF=10mA, RL=50Ω, enabling high-speed switching operations. The forward voltage is 1V max at 100mA, and the capacitance between terminals is 3pF typical at 0.5V and 1MHz. The device is RoHS3 compliant and halogen free, with an operating temperature range up to 125°C and storage temperature from -55°C to +125°C. Power dissipation is 150 mW. The diode is suitable for general-purpose switching applications such as high-speed switching circuits, protection circuits, and signal processing. The gold-plated terminals ensure reliable solderability per MIL-STD-750, method 2026. The package weight is approximately 0.003 grams, and it is supplied in tape and reel packaging for automated assembly.
