TransientVoltage Suppression Diodes

Surface Mount – 200W > SMF Series

RoHS

SMF Series

™

TVS Diode Arrays (SPA Family of Products)

Description

The SMF series is designed speciﬁcally to protect sensitive

electronic equipment from voltage transients induced by

lightning and other transient voltage events.

SMF package is 50% smaller in footprint when compare

to SMA package and deliverying one of the lowest height

proﬁles (1.1mm) in the industry.

Features

(T_A=25^OC unless otherwise noted)

•Compatible with

industrial standard

package SOD-123

• For surface mounted

applications to optimize

board space

• EFT protection of data

lines in accordance with

IEC 61000-4-4 (IEC801-4)

• Low inductance, excellent

clamping capability

• 200W peak pulsepower

capability at 10 x 1000µs

waveform, repetition rate
