SAN JOSE, Calif., Nov. 24, 2025 /PRNewswire/ -- Power management leader, Kinetic Technologies, is expanding its USB Protection portfolio with the introduction of its KTS1287 and KTS1289 flat-clamp transient voltage suppressors (TVS) for ESD and surge events. These monolithic ICs include an active-clamp control circuit, a gate-driver, and a power MOSFET to provide higher performance in a smaller footprint compared to typical TVS diodes. The KTS1287 and KTS1289 will clamp both positive and negative ESD and surge events per IEC standards.

"Compared to traditional TVS diodes, the flat-clamp TVS device provides tight voltage regulation which lowers clamping voltage during a surge event. This allows designers to confidently select system components with a lower voltage tolerance, further lowering system costs and complexity without sacrificing robustness."
– Frank Mao, Senior Director of Marketing at Kinetic Technologies

The KTS1287 addresses surge protection for 20V standard power range (SPR) VBUS components while the KTS1289 is robustly designed to protect 28V extended power range (EPR) VBUS components from Electrical Overstress (EOS) damage in different application scenarios. These devices also provide the highest ESD protection performance in the industry.

The active control circuit of the KTS1287/KTS1289 clamps the voltage nearly flat during ESD/Surge events while high current is shunted to ground through the integrated power MOSFET. Together, the tightly controlled breakdown voltage and the "flat-clamp" performance reduce the peak voltage seen by capacitors and downstream circuits, thereby easing system design and lowering costs.

Key applications for the new KTS1287 and KTS1289 span across any USB or DC Input with 20V _IN(TYP) to 28V_IN(TYP) voltage. These devices are targeted towards the consumer and enterprise markets and are geared for Smartphones, Tablets, Notebooks / PCs, Docking Stations, Terminals, Monitors, Cameras, Power-Banks, Generators, and Rechargeable Devices.
