New TVS array protects high-speed data from ESD

Inelco Hunter offers the availability of the new ProTek Devices PTA03-3.3ULC, a high power, low capacitance TVS hybrid array Gigabit Ethernet Protector. It has been developed to protect high-speed data line applications from the damaging effects of ESD, EFT and secondary transient threats.

The device is a differential-mode port, fast transient protection array that provides ultra-low capacitance using a hybrid TVS and Thyristor structure. It delivers even lower capacitance than its predecessor at 1.5pF (differential mode) @ TJ=75C.

The protection device can withstand 2kW peak pulse power per 1.2/50us - 8/20us Surge Pulse. It allows for further peak current handling capability and provides a very low clamping voltage.

It is supplied in an SOIC-8 package configuration, and the device will be utilised for Gigabit Ethernet applications in telecom equipment. The device protects a single data-line pair and can meet Bellcore GR1089 Surge requirements, also meeting IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 circuit protection requirements.

Other applications include T1/E1 Line Cards, ISDN U-Interfaces, ISDN S/T Interfaces, YUSL Interfaces, Ethernet 10/100/1000 Base T and Set Top Box Interfaces. Samples are provided on request.
