Alpha and Omega Semiconductor Limited (AOS) introduced its AOZ8S205BLS Series transient voltage suppressor (TVS) diodes. These ultra-low capacitance TVS diodes are designed to meet the increasing ESD protection needs in today’s sensitive high-speed line and antenna-based applications. AOZ8S205BLS is engineered using AOS’ innovative high-trigger voltage TVS platform, combined with its advanced packaging and the series’ industry-leading low 0.075 pF capacitance. It is ideal to protect high-speed serial interfaces such as USB4 v2.0 and Thunderbolt 5 that are used in a broad range of electronic systems.
Additional features that boost the protection capabilities of AOZ8S205BLS TVS diodes include lower insertion loss, reverse working voltages (VRWM) of 3.3 V, 5 V, and 24 V, and accurate clamping voltage. The AOZ8S205BLS is a single-channel device housed in a 0.6 × 0.3 mm leadless surface-mount device (SMD), which allows it to meet the small footprint requirement of a USB Type-C connector.
