Alpha and Omega Semiconductor Announces Ultra-Low Reverse Working Voltage TVS Diode for USB4 and Thunderbolt 4 ESD Protection

Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs and modules, today announced the release of its AOZ8S207BLS-01 Ultra-Low Reverse Working Voltage (V_RWM) transient voltage suppressor (TVS) diode. Designed to deliver extremely low capacitance and fast response time, the AOZ8S207BLS-01 TVS diode offers superior high-speed data line protection based on AOS’ advanced Ultra-Low Breakdown Voltage (V_BR) TVS platform and innovative packaging. These features, along with the TVS diode’s 0.15pf capacitance, make it ideal 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. AOZ8S207BLS-01 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. In addition, the AOZ8S207BLS-01 is a single-channel device housed in a 0.6x0.3mm leadless Surface-Mounted Device (SMD) package, so it is particularly well-suited to meet the small footprint requirements of USB Type-C connectors.

“As the leading developer and supplier of ESD protection solutions in high-speed interfaces such as USB, HDMI, and Thunderbolt, this new TVS platform builds on our state-of-the-art portfolio to give our customers 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. This feature-rich TVS diode makes an excellent solution for high-speed data line protection,” said Charles Chen, Marketing Director at AOS. “We believe our new competitive platform will help our partners and customers to greatly reduce ESD failure rates in their electronic products.”
