1.5KE Series
TVS devices are ideal for the protection of I/O interfaces,
V
CC bus and other vulnerable circuits used in telecom,
computer, industrial and consumer electronic applications.
Applications
Features
The 1.5KE Series is designed specically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
