Super Low Capacitance Transient Voltage Suppressor for USB3.2 & Thunderbolt 3.0 Protection

Releases by Alpha and Omega Semiconductor

Alpha and Omega Semiconductor Limited (AOS) today announced the release of AOZ8661BDT-05­ a transient voltage suppressor (TVS) for high-speed line protection using the latest Super Low Cap TVS platform. This new device is ideal for USB Type-C applications such as notebooks and mobile devices.

With such a low capacitance of 0.15pF, AOZ8661BDT-05 is optimized for high-speed line protection including but not limited to USB3.1 Gen2, USB3.2, Thunderbolt 3.0, and avoiding the transmission error by minimizing the capacitance effect. AOZ8661BDT-05 is housed in a 0.6×0.3mm leadless Surface-Mounted Device (SMD) and perfectly suited to fit the small footprint requirement of a USB Type-C connector.

As the leading vendor in ESD protection solution in high-speed interfaces such as USB, HDMI, and Thunderbolt, we have released a new TVS platform that provides a much better figure of merit (FOM) on the clamping voltage times capacitance. In addition to low capacitance, it is also important to have lower clamping voltage and faster response during the ESD event to protect the ESD sensitive chipset. The new platform of Super Low Cap with very low capacitance and very low clamping voltage is ideal for high-speed line protection,” said Michael K. S. Ng, Sr. Marketing Manager of TVS Product Line at AOS. “We believe the new competitive platform will contribute to reducing the ESD failure rate in our partners and customers’ electronic products.”
