TVS uses Super Low Cap TVS technology and packaging
Alpha and Omega Semiconductor has announced a two-in-one low capacitance transient voltage suppressor (TVS) for USB4.0, Thunderbolt 4.0 and HDMI2.1 protection.
There are two devices, the AOZ8S204BL2 and AOZ8S205BL2 two-in-one TVS for super high speed line protection using the latest Super Low Cap TVS platform and advanced packaging. The TVS devices are suitable for USB Type-C and HDMI applications such as notebooks, desktop PC, game console, and 4K and 8K TVs.
Capacitance is 0.15pF and 0.075pF for the AOZ8S204BL2 and AOZ8S205BL2 respectively. The devices are optimised for super high-speed line protection including, but not limited to USB4.0, Thunderbolt 4.0, HDMI2.1 and avoiding the transmission error by minimising the capacitance effect.
The AOZ8S204BL2 and AOZ8S205BL2 are two channels devices (two-in-one) and housed in a 0.63 x 0.33mm leadless surface mount device and fit the small footprint requirement of a USB Type-C connector.
The two-in-one low capacitance device provides a pin-out for differential signal and saves space in high-speed interface applications. The format also reduces the part counts on circuit board. AOS believes the two-in-one with low capacitance approach benefits customers to accomplish the best design and logistics management.
For ESD protection, in addition to low capacitance, it is also important to have a lower clamping voltage and faster response during the ESD event to protect the ESD-sensitive chipset, explained Charles Chen, marketing director of TVS product line at AOS. “The new platform of Super Low Cap with very low capacitance and very low clamping voltage is ideal for high-speed line protection. We believe the new competitive platform will reduce the ESD failure rate in our partners and customers’ electronic products,” he said.
The TVS devices are immediately available in production quantities with a lead time of 20 weeks.
