Alpha and Omega Semiconductor Limited (AOS) today announced the release of AOZ8S204BL2 and AOZ8S205BL2 a 2-in-1 transient voltage suppressor (TVS) for super high-speed line protection using the latest Super Low Cap TVS platform and advanced packaging. These new devices are ideal for USB Type-C and HDMI applications such as notebooks, desktop PC, game console, and 4K & 8K TVs.
With such ultra-low capacitance of 0.15pF and 0.075pF, AOZ8S204BL2 and AOZ8S205BL2 are optimized for super high-speed line protection including but not limited to USB4.0, Thunderbolt 4.0, HDMI2.1 and avoiding the transmission error by minimizing the capacitance effect. AOZ8S204BL2 and AOZ8S205BL2 are two channels devices (2-in-1) and housed in a 0.63×0.33mm leadless Surface-Mounted Device (SMD) and perfectly suited to fit the small footprint requirement of a USB Type-C connector.
2-in-1 with ultra-low capacitance device provides the best solution for an ideal pin-out for differential signal, space saving of super high-speed interface application, and reduces the part counts on circuit board. We believe this new approach (2-in-1 with ultra-low capacitance device) benefits customers to accomplish the best design and logistics management.
“As the leading vendor in ESD protection solutions 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 a 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 Charles Chen, Marketing Director of TVS Product Line at AOS. “We believe the new competitive platform will reduce the ESD failure rate in our partners and customers’ electronic products.”
