DUAL UNIDIRECTIONAL AND SINGLE BIDIRECTIONAL TVS
Please click here to visit our online spice models database.
General Descriptions
•
This Transient Voltage Suppressor (TVS) diode is designed for
dual unidirectional or single bidirectional protection for data
lines, components or circuits from damage due to electrostatic
discharge (ESD), cable discharge events(CDE) and lightning
(see IPPM below). It offers high ESD capability, low reverse
leakage, low junction capacitance and low clamping voltage
over range of temperature. They are suitable for computers,
communication systems, hand held portables, high density PC
boards and peripherals.
