TVS Hybrid Array Delivers Circuit Protection for High Speed Data Lines

PTA03-3.3ULC Press Release

The New Component Guards Against ESD, EFT, and More in Applications Like Ethernet, Set Top Boxes, and Various Other High Speed Interface Applications

ProTek Devices has introduced a high power, low capacitance, transient voltage suppressor hybrid array designed for circuit protections in common high speed data line applications like Ethernet, set top boxes (STB), xDSL, T1/E1 line cards, and ISDN. The circuit protection provided by the PTA03-3.3ULC includes guarding against damaging effects of ESD, EFT, and secondary electrical transient threats.

The PTA03-3.3ULC TVS hybrid array is designed to provide low capacitance – max 2.4pF (I/O to I/O) – even at higher temperatures. It features 100A (2/10 microseconds) per Bellcore GR1089 (intra-building) and ESD protection greater than 30kV, contact per IEC 61000-4-2. It also allows for a telecom/diode bridge configuration. In addition, it boasts 2000 Watts peak pulse power per Line (typical = 8/20 microseconds).

ProTek Devices’ PTA03-3.3ULC is also compatible with IEC standards 61000-4-2 (ESD): air plus or minus 15kV, contact plus or minus 8kV; with IEC 61000-4-4 (EFT): 40A – 5/50ns; with IEC 61000-4-5 (surge): 70A, 8/20 microseconds. It is also RoHS and REACH compliant.
