DALC208SC6Y Automotive low capacitance diode array for ESD protection Datasheet production data Features Protection of 4 lines Peak reverse voltage: V = 9 V per diode RRM 1 Very low capacitance per diode: C < 5 pF Very low leakage current: I < 1 A R SOT23-6L Benefits Comfort and convenience Cost effective solution compared with discrete solution Figure 1. Functional diagram (top view) High efficiency in ESD suppression No significant signal distortion thanks to very I/O 1 I/O 4 low capacitance High reliability offered by monolithic integration REF 2 REF 1 Lower PCB area consumption versus discrete solution AEC-Q101 qualified I/O 2 I/O 3 Complies with the following standards ISO10605 - C = 150 pF, R = 330 Description 15 kV (air discharge) The DALC208SC6Y diode array is designed to 8 kV (contact discharge) protect components which are connected to data ISO10605 - C = 330 pF, R = 330 and transmission lines from overvoltages caused 8 kV (air discharge) by electrostatic discharge (ESD) or other 8 kV (contact discharge) transients. It is a rail-to-rail protection device also suited for overshoot and undershoot suppression ISO7637-3: on sensitive logic inputs. Pulse 3a: V = -150V s The low capacitance of the DALC208SC6Y Pulse 3b: V = +100V s prevents significant signal distortion. Applications Where ESD and EOS transient overvoltage protection in susceptible equipment is required, such as: Information and entertainment Signal communications Connectivity November 2012 Doc ID 16362 Rev 1 1/12 This is information on a product in full production. www.st.com 12Characteristics DALC208SC6Y 1 Characteristics Table 1.
