APPEARANCE
DESCRIPTION
This SMBJP6KE and SMBGP6KE series is an economical surface mount version of
the popular P6KE axial-leaded series of 600 W Transient Voltage Suppressors
(TVSs). It is available in both unidirectional and bi-directional configurations for
protecting voltage-sensitive components from destruction or degradation. Response
time of clamping action is virtually instantaneous. As a result, they may also be used
effectively 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.
