ITA6V1U1 STMicroelectronics

ITAxxU1 Transil array for data line protection Features High surge capability Transil array: I = 40 A (8/20 s) PP Peak pulse power : 300 W (8/20 s) SO-8 Up to 6 bidirectional Transil functions Low clamping factor (V / V ) at high current CL BR level Figure 1. Functional diagram Low leakage current ESD protection up to 15 kV 8 I/O1 1 I/O6 I/O2 2 7 GND Complies with the following standards IEC 61000-4-2 level 4 I/O3 3 6 GND 15 kV (air discharge) I/O4 4 5 I/O5 8 kV (contact discharge) MIL STD 883G- Method 3015-7: class 3B 25 kV (human body model) Applications Data transmission lines protection, such as: Unipolar signal up to 5.5 V Bipolar signal in the 2.5 V range Description Transil diode arrays provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS technology and low voltage supplied ICs. The ITA series allies high surge capability against energetic pulses with high voltage performance against ESD.
