LCDA24

Low Capacitance TVS Diode Array For High-Speed Data Interfaces

Description

The LCDA series of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD and other voltage-induced transient events. Each device will protect two high-speed lines. They are available with operating voltages of 5V, 12V, 15V and 24V. They are bidirectional devices and may be used on lines where the signal polarities are above and below ground.

TVS diodes are solid-state devices designed specifically for transient suppression. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage and no device degradation. The LCDA series devices feature low capacitance compensation diodes in series with standard TVS diodes to provide an integrated, low capacitance solution for use on high-speed interfaces.

The LCDA series devices may be used to meet the immunity requirements of IEC 61000-4-2, level 4.
