General Description
The UESD54B/55B/56B/57B/64B of TVS diode array is designed to protect sensitive electronics from damage or latch-up due to ESD for use in applications where board space is at a premium. It is unidirectional device and may be used on lines where the signal polarities are above ground. The UESD54B/55B/64B will protect up to four lines, the UESD56B will protect up to five lines and the UESD57B will protect up to six lines.
TVS diodes are solid-state devices feature large cross-sectional area junctions for conducting high transient currents, specifically for transient suppression. It offers desirable characteristics for board level protection including fast response time, low operating, low clamping voltage, and no device degradation.
