Transient Voltage Suppression Diodes
Surface Mount – 3000W > SMDJ series
SMDJ Series
Uni-directional
Bi-directional
Description
RoHS
The SMDJ series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• For surface mounted
applications in order to
optimize board space
• Low profile package
• Typical failure mode is
short from over-specified
voltage or current
• Whisker test is conducted
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
