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.

FEATURES
• Economical series for thru-hole mounting
