SCOTTSDALE DIVISION
600 Watt TRANSIENT VOLTAGE
SUPPRESSOR
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.
