CALMIRCO CM1218-05SO Low capacitance transient voltage suppressors / esd protector Datasheet

CM1218
Low Capacitance Transient Voltage
Suppressors / ESD Protectors
Features
Product Description
•
•
The CM1218 family of devices features transient voltage suppressor arrays that provide a very high level of
protection for sensitive electronic components which
may be subjected to electrostatic discharge (ESD).
•
•
•
•
Low I/O capacitance at 7pF typical
In-system ESD protection to ±15kV contact
discharge, per the IEC 61000-4-2 international
standard
Two, three, four or five channels of ESD protection
Compact SMT package saves board space and
facilitates layout in space-critical applications
Each I/O pin can withstand over 1000 ESD strikes
Lead-free versions available
Applications
•
•
•
High-speed consumer electronic ports
ESD protection of PC ports, including USB ports,
serial ports, parallel ports, IEEE1394 ports,
docking ports, proprietary ports, etc.
Protection of interface ports or IC pins which are
exposed to high ESD levels
All pins of the CM1218 are rated to withstand ±15kV
ESD pulses using the IEC 61000-4-2 contact discharge method. Using the MIL-STD-883D (Method
3015) specification for Human Body Model (HBM)
ESD, all pins are protected from contact discharges of
greater than ±30kV.
The CM1218 is supplied in a number of compact, surface mount packages depending on the channel configuration desired. All versions of this device are
available with optional lead-free finishing.
