ESD Solutions w/ High-Trigger, Ultra-Low Clamping Voltage


Ideal for USB4, Thunderbolt3, PCI Express Protection for Computers and Mobiles

Alpha and Omega Semiconductor Limited (AOS) 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 5V to 20V.  For fast charging such as USB Power Delivery and Quick Charger, traditional TVS diodes for USB protection with breakdown voltage lower than 20V 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.

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.
