ProTek Devices’ New TVS Arrays Deliver ESD, EFT, Surge and Lightning Protection


The PLR0524P, PLR0524 and PLR0521 are Ideal for Protection in Numerous Computing, Consumer Electronics and Telecommunications Devices and Equipment

TEMPE, Ariz. – August 27, 2012 – ProTek Devices™ today introduced three new transient voltage suppressor (TVS) arrays – the PLR0524P, PLR0524 and PLR0521 – which are ideal for providing electrical protection in numerous computing, consumer electronics and telecommunications devices and equipment. Applications for the PLR0524P and PLR0524 include DVI, Gigabit Ethernet, HDMI, and USB interfaces. Other ideal applications include; FireWire (IEEE 1394 to 3.2Gbps); PCIe; and SATA interfaces. Ideal applications for the PLR0521 include Ethernet 10/100/1000 Base T; FireWire; wireless communications devices; and USB interfaces.

PLR0524P and PLR0524 Technical Features
The PLR0524P and PLR0524 are ultra low capacitance (0.4pF typical [I/O to I/O]) steering diode / TVS arrays. They provide protection from electrostatic discharges (ESD); electrical fast transients (EFT); surges; and lightning. The devices protect up to four lines. The PLR0524P and PLR0524 are available in a space-saving DFN-10 package configuration. The PLR0524 is used on very sensitive ASICs that require ultra-low clamping (9V @6A). The PLR0524P has a VC (clamping) of 16V. The PLR0524P can be used on most other PHY applications. They are rated at 60 Watts peak pulse power per line for a 8/20 micro second surge waveform. These devices meet IEC 61000-4-2 ESD: air – 15kV, contact – 8kV; 61000-4-2 EFT requirements. They also meet IEC 61000-4-4 surge and IEC 61000-4-5 lightning: 4A – 8/20 micro second surge waveform requirements. ESD protection from both devices is > 25 kilovolts. The PLR0524P and PLR0524 provide < 0.5 microampere low leakage current. The devices can be used in conjunction with passive components integrated into a TVS / filter network. In this configuration they provide EMI / RFI protection.

PLR0521 Technical Features
The PLR0521 is an ultra low capacitance (0.4 pF typical) TVS array. It provides ESD and EFT protection for one bidirectional line. It meets IEC 61000-4-2 ESD: air 15kV, contact 8kV requirements. It also meets IEC 61000-4-4 EFT and IEC 61000-4-5 surge requirements. It features 80 Watts peak pulse power per line (tp = 8/20 micro second surge waveform). In addition, the PLR0521 has a low clamping voltage and low leakage current and is available in a miniature DFN-2-0402 package. Read more.
