DALC112S1
uLtRA Low CAPACitAnCe SteeRing DioDe ARRAy
DeSCRiPtion
The DALC112S1 is a low capacitance and low leakage steering diode array capable of protecting up to six (6) high
speed data lines. Its ultra low capacitance allows maintenance of signal integrity for high-speed data lines while pro-
tecting the circuit ICs from the damage of severe transients. An extremely low leakage current makes the DALC112S1
suitable for battery powered devices.
The DALC112S1 is available in a SO-8 package. This device meets all the applicable voltage immunity standards,
including IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge).
