rev. 1.0 august 2013 www.aosmd.com page 1 of 7 AOZ8312 low capacitance 2.5 v tvs diode general description the AOZ8312 is a transient voltage suppressor array designed to protect high speed data lines from esd and lightning. this AOZ8312 incorporates twelve low capacitance steering diodes and a tvs in a single package. during transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground. the AOZ8312 may be used to meet the esd immunity requirements of iec 61000-4-2, level 4 and iec 61000-4-5. the tvs diodes provide effective suppression of esd voltages: 30 kv (air discharge) and 30 kv (contact discharge). the AOZ8312 comes in a halogen free and rohs compliant 3.5 mm x 2.5 mm x 0.55 mm dfn-12 package and is rated over a -40 c to +85 c ambient temperature range. the AOZ8312 is compatible with both lead free and snpb assembly techniques. the small size, low capacitance and high esd protection makes the AOZ8312 ideal for protecting high speed video and data communication interfaces. features ? esd protection for high-speed data lines: ? iec 61000-4-2, level 4 (esd) immunity test ? 30 kv (air discharge) and 30 kv (contact discharge) ? iec 61000-4-4 (eft) 40 a (5/50 ns) ? iec 61000-4-5 (lightning) 18 a ? human body model (hbm) 30 kv ? small package saves board space ? low insertion loss ? protects twelve i/o lines ? low clamping voltage ? low operating voltage: 2.5 v ? green product ? pb-free device applications ? video graphics cards ? monitors and flat panel displays ? digital video interface (dvi) ? t1/e1 telecom ports typical application circuit diagram i/o1 i/o2 i/o3 i/o4 i/o12 protection of twelve lines 2 3 4 gnd 1 12 2 3 4 gnd 1 12
