STMicroelectronics ITA25B3
The ITAxxxB3 has been designed with a 4-point structure (separated Input/output) in order to efficiently protect against disturbances with very high di/dt rates, such as ESD. The purpose of this 4-point structure is to eliminate the overvoltage introduced by the parasitic inductances of the wiring (Ldi/dt). With this layout, each line to be protected passes through the protection device.| Part No. | ITA25B3 |

APPLICATIONS
Differential data transmission lines protection : - RS-232 - RS-423 - RS-422 - RS-485FEATURES
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 15kVDESCRIPTION
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.
