Ultra-Low Clamping Voltage High-Surge TVS for USB Type-C

October 17, 2019 by Paul Shepard

Alpha and Omega Semiconductor Limited (AOS) has introduced the AOZ8621UNI, a series of Transient Voltage Suppressor (TVS) for VBUS protection using the latest high-surge TVS platform. This new series is ideal for USB Type-C Power Delivery, including but not limited to laptops and smartphones.

The new AOZ8621UNI series covers a reverse working voltage (VRWM) range from 5V to 22V, which meets the requirement of USB Power Delivery. Required VRWM can be selected according to the maximum operating voltage on the Type-C VBUS pin.

The AOZ8621UNI series is housed in a DFN 2x2 package and is suited to fit the small footprint requirement of Type-C application small electronic devices.

With such low breakdown voltage, low clamping voltage, and high-surge current, AOS believes the new high-surge TVS platform will contribute to reducing the ESD and EOS failure rate in our partners' and customers' products," said Michael K. S. Ng, Sr. Marketing Manager of the TVS product line at AOS.
