过压保护器, 2.2 V至5.5 V输入, SC-70-5

The is a signal line overvoltage protector for low voltage devices in 5 pin SC-70 package. This signal line overvoltage protector for low voltage digital communication ports provides protection against high voltage faults and ESD strikes. It is especially useful for sensitive communication protocols such as maxim 1-wire that cannot afford standard means of fault protection such as large series resistors or large line capacitances. It consumes only 13µA of quiescent supply current. The EXT port is protected up to 28V. The device features a reaction time of 60ns for fast action during fault conditions and operates over the -40°C to +125°C automotive temperature range.
