Ideal for USB 4, Thunderbolt 3, PCI Express Protection for Computers and Mobiles

Alpha and Omega Semiconductor introduced the AOZ8S303BLS-24 and AOZ8S305BLS-24, a series of single-channel Transient Voltage Suppressor (TVS) for high-speed line protection using the best-in-class low capacitance TVS platform. The new products are ideal for Electrostatic Discharge (ESD) protection of Type-C connectors in mobiles, laptops, televisions, and other electronic devices.

USB Type-C with PD (Power Delivery) has become a standard power and data interface of notebook PCs and smartphones, and the voltage range is defined as variable from 5 V to 20 V. For fast charging such as USB Power Delivery and Quick Charger, traditional TVS diodes for USB protection with breakdown voltage lower than 20 V risk getting shorted or damaged. Hence, the corresponding Type-C port will inactivate permanently. To solve this common market problem, AOS proposes two TVS, AOZ8S303BLS-24 and AOZ8S305BLS-24. Their high reverse working voltage covers the whole voltage range from a USB PD port. In addition, the Ultra-Low-Clamping Voltage and Capacitance are optimized for ESD protection in high-speed lines, including but not limited to USB, Thunderbolt, HDMI, and PCI Express, by minimizing the capacitance effect.

“Type-C connectors are widely applied in electronics devices. The new products housed in a standard WLCSP 0.6×0.3-2 (0201) package, and its small form factor is ideal for high-speed differential signals in Type-C. Both AOZ8S303BLS-24 and AOZ8S305BLS-24 will not only contribute to reducing the ESD failure rate but also reducing the failure of Short-to-VBUS in our partners’ and customers’ electronic products,” said Michael K. S. Ng, Sr. Marketing Manager of the TVS product line at AOS.

Pricing and Availability

The AOZ8S303BLS-24 and AOZ8S305BLS-24 are immediately available in production quantities with a lead-time of 20 weeks. The unit price for 1,000 pieces is $0.20.
