® ITA6V5B3 / ITA10B3 ITA18B3 / ITA25B3 BIDIRECTIONAL TRANSILTM ARRAY FOR DATALINE PROTECTION Application Specific Discretes A.S.D.TM APPLICATIONS Differential data transmission lines protection : - RS-232 - RS-423 - RS-422 - RS-485 FEATURES HIGH SURGE CAPABILITY TRANSIL ARRAY IPP = 40 A (8/20µs) PEAK PULSE POWER : 300 W (8/20µs) SEPARATED INPUT-OUTPUT UP TO 9 BIDIRECTIONAL TRANSIL FUNCTIONS LOW CLAMPING FACTOR (VCL / VBR) AT HIGH CURRENT LEVEL LOW LEAKAGE CURRENT ESD PROTECTION UP TO 15kV DESCRIPTION Transil diode arrays provide high overvoltage protectionby 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. The separated input/output configuration of the device ensures improved protection against very fast transient overvoltage like ESD by elimination of the spikes induced by parasitic inductances created by external wiring.
