Texas Instruments SN65220 Single Universal Serial Bus Port Transient Suppressor SN65220DBVTG4

The SN65220 is a dual unidirectional transient voltage suppressor designed to protect USB low and full-speed ports from electrical noise transients. It features a stand-off voltage of 6 V and offers ESD protection capabilities that exceed 15 kV for the human body model and 2 kV for the machine model. The device has a low leakage current of 1 µA maximum at 6 V and a typical input capacitance of 35 pF, which may limit its suitability for high-speed USB 2.0 applications. The SN65220 is available in a compact SOT-23 package and operates within a temperature range of -40°C to 85°C. Proper board design and layout techniques are essential to achieve optimal ESD performance.
