P5KE5.0 thru P5KE170CA, e3
500 W TRANSIENT VOLTAGE
SUPPRESSOR
SCOTTSDALE DIVISION
DESCRIPTION
This P5KE series is an economical 500 W Transient Voltage Suppressor
(TVS) for protecting voltage-sensitive components from destruction or
degradation.
It is available in both unidirectional and bi-directional
configurations as well as RoHS Compliant (annealed matte-Tin Finish) with
an e3 suffix added to the part number. The response time of their 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.
