® ESDALC6V1P6
QUAD LOW CAPACITANCE TRANSIL™ ARRAY
ASD™
FOR ESD PROTECTION
MAIN APPLICATIONS
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.
FEATURES
■ 4 Unidirectional Transil™ functions
■ Breakdown voltage VBR = 6.1 V min.
■ Low diode capacitance (12pF @ 0V)
■ Low leakage current < 500 nA
■ Very small PCB area < 2.6 mm2
SOT-666IP

FUNCTIONAL DIAGRAM
DESCRIPTION
The ESDALC6V1P6 is a monolithic array
designed to protect up to 4 lines against ESD
transients.
The device is ideal for situations where board
space saving is required.

The measurements done here after show very clearly (figure A5) the high efficiency of the ESD protection:
the clamping voltage V(i/o) becomes very close to VBR (positive way, figure A5a) and -VF (negative way,
figure A5b).

a: Response in the positive way
b: Response in the negative way
One can note that the ESDALC6V1P6 is not only acting for positive ESD surges but, also, for negative
ones. For this kind of disturbances, it clamps close to ground voltage as shown in figure A5b.
