DESCRIPTION
APPEARANCE
The Transient Voltage Suppressor (TVS) series for 1N5908 & 1N6267-1N6303A
are JEDEC registered selections for unidirectional devices. The popular series of
1.5KE6.8-1.5KE400CA offers similar voltages with an extended voltage range
and also provides bidirectional options with a C or CA suffix. All have the same
high Peak Pulse Power rating of 1500 W and extremely fast response time. They
can protect from secondary lightning effects per IEC61000-4-5 and class levels
protection. Since their response time is virtually instantaneous, they can also
protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

FEATURES
APPLICATIONS / BENEFITS
Economical TVS series for thru-hole mounting
Available in both Unidirectional and Bidirectional
(1.5KE series add C or CA suffix for Bidirectional)
Voltages from 6.8 to 400 V Breakdown (VBR)
Suppresses transients up to 1500 watts @ 10/1000 s
Optional 100% screening for avionics grade is
available by adding MA prefix to part number for added
100% temperature cycle -55
oC to +125oC (10X) as well
as surge (3X) and 24 hours HTRB with post test VZ &
IR (in the operating direction for unidirectional or both
directions for bidirectional)
Options for screening in accordance with MIL-PRF-
19500 for JAN, JANTX, and JANTXV are also available
by adding MQ, MX, or MV prefixes respectively to part
numbers.
Surface mount equivalent packages are available as
SMCJ5.0 - SMCJ170CA or SMCG5.0 - SMCG170CA
(consult factory for other surface mount options)
Moisture classification is Level 1 with no dry pack
required per IPC/JEDEC J-STD-020B
RoHS Compliant devices available by adding “e3” suffix
