UCLAMP0505A Datasheet, PDF (1/8 Pages) Semtech Corporation – μClampTM 5-Line ESD protection Array

PROTECTION PRODUCTS - MicroClamp^TM
Description
The µClamp^TM series of TVS arrays are designed to pro-
tect sensitive electronics from damage or latch-up due
to ESD. They are designed for use in applications where
board space is at a premium. Each device requires less
than 2.9mm² of PCB area and will protect up to five lines.
They are unidirectional devices and may be used on lines
where the signal polarities are above ground.
TVS diodes are solid-state devices designed specifically
for transient suppression. They feature large cross-sec-
tional area junctions for conducting high transient cur-
rents. They offer desirable characteristics for board level
protection including fast response time, low operating
and clamping voltage, and no device degradation.
The uClamp^TM0505A may be used to meet the immunity
requirements of IEC 61000-4-2, level 4. The small SC89
package makes them ideal for use in portable electron-
ics such as cell phones, PDA’s, notebook computers, and
digital cameras. These devices feature a lead-free, matte
tin lead finish. They are compatible with both lead free
and SnPb assembly techniques.
