Quad TVS Arrays Protect CMOS Circuitry

The PJQMS05 from PanJit offers Quad TVS arrays with low clamping voltage, low capacitance, and low leakage current. PanJit has developed a second version of the PJSMS05 in a smaller, QFN 2-mm x 2-mm package, similar in size to the SC70-6L, to provide surge and ESD protection for four data lines.

Designed to protect 5-V CMOS circuitry, the also features very low capacitance, therefore minimizing insertion loss and enabling faster data transmission. In addition, the PJQMS05 features low leakage current and therefore offers a reduction in signal and overall system power loss. The new product is expandable for use at other logic voltage levels. The PJSMS05 meets the IEC 61000-4-2 ESD standard as well as the IEC 61000-4-5 surge standard.

The PJQMS05 is similar to the PJSMS05 and comes with the same electrical specification. However, it also comes in a very low profile package called a QFN 2x2, with a max. area of 2 mm X 2 mm and a max. height of 0.9 mm (0.75 mm available). Peak power dissipation is 350 W with an 8X20µs surge waveform. It also fully complies with the IEC61000-4-2 standard. Applications include SIM card ports, personal digital assistants (PDA), portable instrumentation and other consumer portable electronic equipment.
