CM1230
2, 4, and 8-Channel
Low-Capacitance ESD
Protection Array
Product Description
The CM1230 is a family of 2, 4 and 8 channel, very low capacitance
ESD protection diode arrays in a CSP form factor. It is ideal for

protecting systems with high data and clock rates or for circuits that
need low capacitive loading. Each channel consists of a pair of ESD
diodes that act as clamp diodes to steer ESD current pulses to either the
positive or negative supply rail. A Zener diode is integrated between the
positive and negative supply rails. The VCC rail is protected from ESD
strikes and eliminates the need for a bypass capacitor to absorb positive
ESD strikes to ground. Each channel can safely dissipate ESD strikes of
±8 kV, meeting the Level 4 requirement of the IEC61000â4â2
international standard as well as ±15 kV air discharges per the
IEC61000â4â2 specification. Using the MILâSTDâ883 (Method

cannot be tolerated when high data rates are transferred between the
baseband choppiest and the LCD driver/controller Is. Higher
capacitive loading normally causes the rise and fall times to slow
which hampers the functionality of circuit and operation of the
wireless handset. The CM1230 incorporates OptiGuardt which
results in improved reliability at assembly. The CM1230 is available in
a spaceâsaving, low profile Chip Scale Package with
RoHSâcompliant, leadâfree finishing.
