Kinetic Technologies KTS1289 Flat-Clamp Mini Monolithic TVS ICs

Kinetic Technologies KTS1289 Flat-Clamp Mini Monolithic Transient Voltage Suppression (TVS) Integrated Circuits (ICs) provide robust TVS protection against Electrostatic Discharge (ESD) and surge events at a system’s USB or other DC power input or output ports. The monolithic ICs include an active-clamp control circuit, a gate driver, and a power MOSFET, providing higher performance in a smaller footprint than typical TVS diodes. The KTS1289 clamps both positive and negative ESD and surge events per IEC standards. The KTS1289 family is packaged in an advanced, fully Green-compliant, 1.66mm x 1.56mm, 6-bump Wafer-Level Chip-Scale Package (WLCSP) or FCDFN22-6 package.

The maximum reverse working voltage and the breakdown voltage of the Kinetic Technologies KTS1289 are set appropriately just above the typical supply voltage. The active control circuit 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.
