ESDALC6V1Px
Low capacitance Transil™ arrays for ESD protection
Datasheet − production data
Description
The ESDALC6V1Px are monolithic suppressors
designed to protect components connected to
data and transmission lines against ESD.

627,3
Features
These devices clamp the voltage just above the
logic level supply for positive transients and to a
diode drop below ground for negative transients.
Figure 1. ESDALC6V1P3 functional diagram
• 2 to 4 unidirectional Transil functions
• Breakdown voltage VBR = 6.1 V min.
• Low leakage current < 100 nA
• Low capacitance (7.5 pF at 3 V)
• Very small PCB area < 2.6 mm2
Benefits
• High ESD protection level
• High integration
Figure 2. ESDALC6V1P5 functional diagram
Complies with the following standards:
• IEC 61000-4-2 (exceeds level 4)
– 15 kV (air discharge)
– 8 kV (contact discharge)
• MIL STD 883E-Method 3015-7: class3
– 25 kV HBM (human body model)
Applications
Figure 3. ESDALC6V1P6 functional diagram
Where transient overvoltage protection in ESD
sensitive equipment is required, such as:
• Automotive applications
• Computers
• Printers
• Communication systems
• Cellular phone handsets and accessories
• Wireline and wireless telephone sets
• Set-top boxes
