The Texas Instruments SN65220DBVR is a dual-channel, uni-directional transient voltage suppressor (TVS) designed to protect USB 2.0 low and full-speed ports from electrical noise transients. It is housed in a surface-mount SOT-23-6 package measuring 2.9 x 2.8 mm.
Key electrical specifications include a reverse stand-off voltage (Vrwm) of 6 V, a minimum breakdown voltage of 6.5 V, and a maximum leakage current of 1000 nA. The device offers a peak pulse power of 60 W (8/20 µs) and a peak pulse current of 3 A per IEC 61000-4-5. Its typical capacitance is 35 pF, which makes it suitable for low and full-speed USB applications but not for high-speed USB 2.0.
The SN65220DBVR provides system-level ESD protection exceeding 15 kV (Human Body Model) and 2 kV (Machine Model). It is designed to protect submicron 3-V or 5-V circuits and is rated for an operating temperature range of -40°C to 85°C.
