KTA1552EDT-TR Description

Short technical summary and product information.

The KTA1552EDT-TR is a quad channel active EMI and ESD suppressor from Kinetic Technologies, designed for Ethernet applications. It integrates patented Active Choke technology to provide up to 10dB of common mode noise suppression over 1MHz to 125MHz when used with Ethernet magnetics, helping systems meet CISPR22 and FCC Part 15 Class B requirements.

The device includes robust built-in ESD suppressors that protect the Ethernet PHY from transient overvoltage events, with IEC 61000-4-2 air discharge protection of ±25kV and contact discharge of ±12kV. It also meets JESD22-A114 HBM ESD of ±8kV and cable discharge event (CDE) of ±12kV.

The KTA1552 operates from a single 2.5V or 3.3V power rail and features an open drain output stage that can be biased from 1.8V to 3.3V using a transformer center-tap supply. Typical power consumption is 90mW. The device is available in a 36-pin DFN package (9mm x 4mm) with exposed pad for surface mount assembly, operating over the industrial temperature range of -40°C to +85°C.
