| ESDA14V2-4BF3 Quad bidirectional TransilTM array for ESD protection Features 4 Bidirectional Transil functions ESD Protection: IEC61000-4-2 level 4 Stand off voltage: 12 V Min. Low leakage current < 0.5 A 50 W Peak pulse power (8/20 s) Flip Chip (5 bumps) Benefits High ESD protection level High integrationSuitable for high density boards Suitable for high density boards Figure 1. Pin layout (bump side) 3 2 1 A B C Complies with the following standards: IEC 61000-4-2 - 15 kV (air discharge) - 8 kV (contact discharge) MIL STD 883E- Method 3015-7: class3 - 25 kV (human body model) Figure 2. Configuration A1 A3 C1 C3 Applications Where transient overvoltage protection in ESD sensitive equipment is required, such as : Computers B2 Printers Communication systems and cellular phones Video equipment GND Description The ESDA14V2-4BF3 is a monolithic array designed to protect up to 4 lines in a bidirectional way against ESD transients.The device is ideal for situations where board space saving is requested. This device is particularly adapted to the protection of symmetrical signals. TM: Transil is ASD a trademark of STMicroelectronics.
