TDK Corporation presents a new EPCOS gas-filled surge arrester. This component consists of a stack of five individual arresters and was developed specifically to protect the power supplies of telecommunications equipment. Its rated DC operating voltage is 48 V DC plus 20 percent according to IEC 61643-11. The special feature of this arrester is its reliable quenching of an applied DC voltage.

The arrester stack with a type designation of LN8-A1400DC-5 measures a compact 16.3 x 8.4 x 8.9 mm3 and thus takes up significantly less space than five discrete arresters.

This protective component has a surge current capability of 20 kA at an impulse wave of 8/20 μs and 4 kA at an impulse wave of 10/350 μs. The arrester conforms to climatic category 40/ 90/ 21 of IEC 600068-1 and is designed for operating temperatures from -40 to +90 °C. With an extremely low capacitance of less than 1 pF (1 MHz) and a high insulation resistance of more than 10 GΩ (100 V DC), this RoHS-compatible SMD component has negligible parasitic coefficients.

The LN8-A1400DC-5 arrester is also available on tape and reel for automated SMD placement with the type designation LN8A-A1400DC-5.
