SR70
ultRa low caPacitance SteeRing diode aRRay
deScRiPtion
The SR70 is an ultra low capacitance steering diode array. Designed for protection against Electrostatic Discharge
(ESD), Electrical Fast Transients (EFT) and secondary lightning threats, this device is ideal for use in high-speed signal
interface application such as USB, microprocessor bus and mobile electronics.
The SR70 is capable of protecting one line pair or two single lines via the steering of transient voltage to power lines
or ground. Its ultra low capacitance allows maintenance of signal integrity for high-speed data lines while protecting
the circuit ICs from the damage of severe transients. An extremely low leakage current makes the SR70 suitable for
battery powered devices and POE applications. The SR70 is available in the small SOT-143 package, which reduces
internal lead inductance for low, overshoot voltage during fast front time transient events like ESD. This device meets
the IEC 61000-4-2 and IEC 61000-4-4 requirements.
