P5KE5.0 thru 170CA
DESCRIPTION APPEARANCE
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 ap plications.
DO-41
(DO-204AL)
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
