The SMA6J series is designed speciﬁcally to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.

Applications

TVS devices are ideal for the protection of I/O Interfaces,

bus and other vulnerable circuits used in Telecom,

Computer, Industrial and Consumer electronic applications.

• For surface mounted

applications to optimize

board space

• Low prole package

• Typical failure mode is

short from over-speciﬁed

voltage or current

based on JEDEC

JESD201A per its table 4a

and 4c

• IEC-61000-4-2 ESD

15kV(Air), 8kV (Contact)

• ESD protection of data

lines in accordance with

IEC 61000-4-2 (IEC801-2)

• EFT protection of data

lines in accordance with

IEC 61000-4-4 (IEC801-4)

• Built-in strain relief

• Glass passivated junction

• Low inductance

• Excellent clamping

capability

• 600W peak pulsepower

capability at 10/1000µs

waveform, repetition rate

(duty cycle): 0.01%
