UESD55B - Quad/Five Line ESD Protection Diode Array

Download the UESD55B datasheet PDF. This datasheet also covers the UESD54B variant, as both devices belong to the same quad/five line esd protection diode array family and are provided as variant models within a single manufacturer datasheet.

General Description

The UESD54B/55B/56B/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.

UESD54B/55B/56B/64B Quad/Five Line ESD Protection Diode Array UESD54B SC70-5/SC88A/SOT353 UESD55B SC89-6/SOT563/SOT666 UESD56B SC89-6/SOT563/SOT666 UESD64B SC89-5/SOT553/SOT665 General Description The UESD54B/55B/56B/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 and the UESD56B will protect up to five lines. TVS diodes are solid-state devices feature large cross-sectional area junctions for conducting high transient currents, specifically for transient suppression.
