SMA6J Series
Uni-directional
Bi-directional
Description
Pb
e3
The SMA6J series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• Small DO-214AC SMT
footprint for minimal board
space requirement
• Typical failure mode is a
short circuit condition for
current events exceeding
component rating
• Whisker test is conducted
based on JEDEC
JESD201A per its table 4a
and 4c
• IEC 61000-4-2 ESD
30kV(Air), 30kV (Contact)
• ESD protection of data
lines in accordance with
IEC 61000-4-2
• 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%
• Fast response time:
typically less than 1.0ps
from 0 Volts to V

bus and other vulnerable circuits used in
Telecom, Computer, Industrial and Consumer electronic
applications.
Notes:
1. Non-repetitive current pulse, per Fig.4 and derated above T
J
(initial) =25ºC per Fig. 3.
2. Mounted on 5.0x5.0mm copper pad to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
component only.
