TVS devices are ideal for the protection of I/O interfaces,
VCC bus and other vulnerable circuits used in telecom,
computer, industrial and consumer electronic applications.
Applications
Features
The 3KP Series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by
lightning and other transient voltage events.
