ESDA14V2-2BF3 Quad bidirectional Transil array for ESD protection Features 2 bidirectional Transil functions ESD protection: IEC 61000-4-2 level 4 Stand off voltage: 12 V Min. Low leakage current 2 Very small PCB area < 1.5 mm Flip Chip (4 bumps) 400 microns pitch Complies with the following standards Figure 1. Pin layout (bump side) IEC 61000-4-2 15 kV (air discharge) 2 1 8 kV (contact discharge) MIL STD 883E- Method 3015-7: class 3 A 25 kV (human body model) Applications B Where transient overvoltage protection in ESD sensitive equipment is required, such as: Computers Figure 2. Configuration Printers Communication systems and cellular phones 12 Video equipment A Description The ESDA14V2-2BF3 is a monolithic array designed to protect 2 lines against ESD transients. The device is ideal for applications B where both reduced line capacitance and board space saving are required. This device is particularly adapted to the protection of symmetrical signals.
