The AOZ8S207BLS-01 ultra-low reverse working voltage (VRWM) transient voltage suppressor (TVS) diode. It is designed to deliver low capacitance and fast response times, with high speed data line protection based on AOS’ Ultra-Low Breakdown Voltage (VBR) TVS platform and packaging. Together with the TVS diode’s 0.15pf capacitance, it is suitable for USB4 and Thunderbolt 4 electrostatic discharge (ESD) protection.

Low breakdown voltage is essential for ESD protection devices, especially when protecting ICs manufactured with the finest process, explains the company. This TVS diode features an especially low breakdown voltage, and it can provide a faster response time compared to conventional snap-back devices, enabling it to absorb ESD energy extremely quickly to avoid damage to the IC and surrounding components.

The single-channel device is housed in a 0.6 x 0.3mm leadless surface-mounted device (SMD) package which makes it well-suited to meet the small footprint requirements of USB Type-C connectors, adds the company.

According to AOS’ marketing director, Charles Chen, the AOZ8S207BLS-01 provides “a much better figure of merit (FOM) on clamping voltage times capacitance”.

“In addition to low capacitance, having a lower clamping voltage and faster response during an ESD event is important to protect today’s more ESD-sensitive chipsets,” and help designers to “greatly reduce ESD failure rates in their electronic products”.

The AOZ8S207BLS-01 TVS diode is immediately available in production quantities with a lead time of 16 weeks.
