Flat-Clamp Mini TVS for High Voltage Surge & ESD Protection

Description

The KTS1287 family provides robust transient voltage suppression (TVS) for ESD and surge events that occur at a system’s USB or other DC power input or output port. The monolithic IC includes 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 clamps both positive and negative ESD and surge events per IEC standards.

The KTS1287 family includes numerous versions, each optimized for a different supply voltage in common use. The maximum reverse working voltage and the breakdown voltage 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.

The KTS1287 is packaged in advanced, fully “green” compliant, 1. 66mm x 1.56mm, 6-bump Wafer-Level Chip-Scale Package (WLCSP) or FCDFN22-6 Package.
