30KPA Series
Please refer to http://www.Littelfuse.com/series/30KPA.html for current information.
30KPA Series
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 30KPA Series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
