® ESDA14V2-4BF1
QUAD BIDIRECTIONAL TRANSIL™ ARRAY
ASD™
FOR ESD PROTECTION
APPLICATION
Where transient overvoltage protection in ESD
sensitive equipment is required, such as :
■ Computers
■ Printers
■ Communication systems and cellular phones
■ Video equipment
This device is particularly adapted to the
protection of symmetrical signals.

DESCRIPTION
The ESDA14V2-4BF1 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.
FEATURES
■ 4 Bidirectional Transil™ functions
■ ESD Protection: IEC61000-4-2 level 4
■ Stand off voltage: 12 V MIN.
■ Low leakage current < 1 µA
■ 50W Peak pulse power (8/20µs)
Flip-Chip
(5 bumps)

The measurements done here after show very clearly (figure A4) the high efficiency of the ESD protection:
the clamping voltage V(i/o) becomes very close to VBR (positive way, figure A4a) and -VBR (negative way,
figure A4b).
