Transient Voltage Suppressor
The SMCJ5.0-170A or SMCG5.0-170A series of 1500 W Transient Voltage
Suppressors (TVSs) protects a variety of voltage-sensitive components from
destruction or degradation. It is available in J-bend design (SMCJ) with the
DO-214AB package for greater PC board mounting density or in a Gull-wing
design (SMCG) in the DO-215AB for visible solder connections. Selections
include unidirectional and bidirectional. They can protect from secondary
lightning effects per IEC61000-4-5 and class levels defined herein, or for
inductive switching environments and induced RF protection. Since their
response time is virtually instantaneous, they can also be used in protection
from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
NOTE: All SMC series are
equivalent to prior SMM package
Economical surface mount design in both J-bend or
Gull-wing terminations
Available in both Unidirectional and Bidirectional
construction with a C or CA suffix
Suppresses transients up to 1500 watts @ 10/1000 µs
Qualified to UL497B
Optional 100% screening for avionics grade is
available by adding MA prefix to part number for added
100% temperature cycle -55oC 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, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers.
Axial-lead equivalent packages for thru-hole mounting
available as 1.5KE6.8 to 1.5KE200CA or 1N6267 thru
1N6303A and 1N5908 (consult factory for other
surface mount options)
