Applications
2.Mounted on 5.0x5.0mm copper pad to each terminal.
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.
3.Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
device only.
