CDSOD323-T03 Description

Short technical summary and product information.

The Bourns CDSOD323-T03 is a unidirectional TVS (Transient Voltage Suppression) diode designed to protect sensitive electronics from voltage transients. It features a working peak voltage of 3.3V, a minimum breakdown voltage of 4V, and a maximum clamping voltage of 7V at 1A. The typical clamping voltage at 20A (8/20µs) is 19V, with a peak pulse power rating of 350W.

 

This diode offers low leakage current of 5µA at working voltage and low capacitance of 3pF typical at 0V and 1MHz, making it suitable for high-speed signal lines. It is rated for operating temperatures from -55°C to 150°C.

 

The device is housed in a surface-mount SOD-323 package (SC-76), which is compatible with standard pick-and-place assembly. It is RoHS compliant and lead-free, suitable for general-purpose applications such as cellular phones, PDAs, notebooks, digital cameras, MP3 players, and USB interfaces.
