P5KE5.0 thru P5KE170CA
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. 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.
