µClamp^TM

4-Line ESD protection Array

PROTECTION PRODUCTS - MicroClamp^TM

Features

Description

The µClamp^TMseries 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 2.9mm²of PCB area and will protect up to four

lines. They are unidirectional devices and may be used

on lines with positive signal polarities.

Transient protection for data lines to

IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)

IEC 61000-4-4 (EFT) 40A (5/50ns)

Protects four unidirectional I/O lines

Ultra-small SC-89 package (1.7 x 1.7 x 0.6mm)

requires less than 2.9mm²of PCB area

Working voltage: 3.3V

Low leakage current

Low operating and clamping voltages

Solid-state silicon-avalanche technology

The µclamp^TM3304A is constructed using Semtech’s pro-

prietary EPD process technology. The EPD process pro-

vides low standoff voltages with significant reductions in

leakage currents and capacitance over silicon-avalanche

diode processes. They feature a true operating voltage Mechanical Characteristics

of 3.3 volts for superior protection when compared to

traditional pn junction devices.

SC-89 (SOT-666) package

Molding compound flammability rating: UL 94V-0

These devices may be used to meet the immunity re-

quirements of IEC 61000-4-2, level 4. They offer desir-

able characteristics for board level protection including

fast response time, low operating and clamping voltage,

and no device degradation. The small SC89 package

makes them ideal for use in portable electronics such as

cell phones, PDAs, notebook computers, and digital cam-

eras.
