ITA6V1U1 ® Application Specific Discretes A.S.D.TM TRANSILTM ARRAY FOR DATALINE PROTECTION APPLICATIONS Data transmission lines protection : - Unipolar signal up to 5.5V - Bipolar signal in the +/- 2.5V range FEATURES HIGH SURGE CAPABILITY TRANSIL ARRAY IPP = 40 A (8/20µs) PEAK PULSE POWER : 300 W (8/20µs) UP TO 6 UNIDIRECTIONAL TRANSIL FUNCTIONS LOW CLAMPING FACTOR (VCL / VBR) AT HIGH CURRENT LEVEL LOW LEAKAGE CURRENT ESD PROTECTION UP TO 15kV ■ SO-8 ■ ■ ■ ■ ■ FUNCTIONAL DIAGRAM 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 IC’s. The ITA series allies high surge capability against energetic pulses with high voltage performance against ESD.
