Product of the month - June 2008

ProTek Device introduces the PLR family- These steering diode TVS arrays support 2 (PLR0502), 4 (PLR0504) or 8 (PLR0508) lines of protection and has an ultra-low capacitance of 1,5pF (typical). The devices are designed to protect high speed serial interface applications, which require very low capacitance loading. The embedded TVS functions to protect the VCC bus, the steering diodes steer the ESD event to either VCC or GND. Other applications include PCIx Ports, USB2,0 Ports, IEEE-1394 Serial ATA, DVI/HDMI ports, digital recorders, DVD-RV drives and test and communication equipment.

The PLR Series is ideally suited to protect multiple data-lines of I/O ports against ESD and EFT. These devices meet the requirements of the IEC 61000-4-2 (ESD) and 61000-4-4 (EFT). At higher operating frequencies or faster edge rates, insertion loss and signal integrity are the major concern. These devices in conjunction with passive components integrated into a TVS/ filter network can be used for EMI/RFI protection. The PLR should be placed near a connector or a sensitive IC component.
