Transient Voltage Suppression Diodes

Axial Leaded – 400W > P4KE series

P4KE Series

RoHS

TVS devices are ideal for the protection of I/O interfaces,

CC bus and other vulnerable circuits used in telecom,

computer, industrial and consumer electronic applications.

Applications

Features

The P4KE Series is designed speciﬁcally to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.
