DESCRIPTION
APPEARANCE
The SMBJ2K3.0-5.0 or SMBG2K3.0-5.0 series of surface mount 2000 Watt
unidirectional Transient Voltage Suppressors (TVSs) provide low voltage
transient protection in a Working Standoff Voltage (VWM) selections from 3.0
to 5.0 volts. Response time of clamping action is virtually instantaneous and
may also be used for protection from ESD or EFT per IEC61000-4-2 and
IEC61000-4-4, or for inductive switching environments and induced RF.
They can also be used for protecting other sensitive components from
secondary lightning effects per IEC61000-4-5 and class levels defined
herein. Microsemi also offers numerous other TVS products to meet higher
and lower power demands and special applications. Also available in military
equivalent screening levels by adding a prefix identifier as further described
in the Features section. Microsemi also offers numerous other TVS products
to meet higher and lower power applications.

FEATURES
APPLICATIONS / BENEFITS
Suppresses transients up to 2000 watts @ 8/20 s (see
Figure 1 and 2)
Fast response
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 available by adding
MQ, MX, or MV prefixes respectively to part numbers.
