DESCRIPTION
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 (V
WM
) 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.
