CDBUR0340 Description

Short technical summary and product information.

The CDBUR0340 is a surface-mount Schottky barrier diode from Comchip Technology, designed for low forward voltage and fast switching applications. It features a maximum reverse voltage of 40V and an average rectified current rating of 350mA. The diode has a typical forward voltage of 600mV at 200mA (370mV at 20mA) and a reverse recovery time of 6.4ns, making it suitable for high-frequency rectification.

 

Electrical characteristics include a maximum reverse current of 5µA at reverse voltages up to 30V, a typical junction capacitance of 50pF, and a peak forward surge current rating of 1.5A (8.3ms). The junction temperature is rated up to 125°C, with a storage temperature range of -65°C to +125°C. Thermal resistance from junction to ambient is 150°C/W.

 

The device is housed in an ultra-thin 0603/SOD-523F package with no leads, gold-plated terminals, and a cathode band for polarity indication. It is RoHS3 compliant and halogen free, suitable for environmentally sensitive designs. Typical applications include low-voltage rectification, polarity protection, and DC-DC converter freewheeling diodes.
