PR Newswire (US)
CM1242-33CP Provides Robust 30kV of Bi-Directional ESD Protection
in a 0201 Single Channel Format MILPITAS, Calif., Dec. 21
/PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD)
today announced the CM1242-33CP, first in a family of extremely
small outline ESD (electrostatic discharge) protection devices.
Establishing new industry benchmarks for ESD performance and small
solution form factor, the CM1242 is an ideal solution for space
constrained applications in multimedia smart phones, netbooks and
MIDs (mobile internet devices), e-book readers and personal media
players. The device provides a single channel of bi-directional +/-
30kV contact ESD protection in a very compact outline (0.6mm x
0.3mm). (Photo:

Protection With multiple ESD ingress points, such as side function
keys and individual keys in a keypad array, designers of smart
phones need to pay particular attention to ESD design criteria. The
robustness of the ESD protection, physical size and price are all
important design considerations. Varistors, popular for their small
size and low cost, also have high clamping voltages, slower
response times than semiconductor based diode solutions and ESD
performance which significantly degrades after each ESD event; as a
result, they are not very effective. When compared to other
semiconductor based solutions, the CM1242-33CP offers performance
and form factor advantages. With an extremely low dynamic
resistance specification of 0.4 Ohm, the CM1242 features a lower
clamping voltage and more robust ESD protection than competing
solutions. An ESD protection device is only effective if it can
shunt the majority of an ESD strike's energy to ground. This
ability is a function of the protection device's dynamic
resistance, which should be as low as possible. If the ESD
protection device has a high dynamic resistance, energy that
normally would be channeled through the ESD protection device will
instead be allowed to reach the device under protection (DUP),
resulting in a higher probability of damage. Key Features Features
include: -- Extremely small 0201 standard package (0.6mm x 0.3mm)
-- Bi-directional +/- 30kV contact discharge ESD protection per
IEC61000-4-2 standard -- Low clamping voltage of +/- 8.6V --
Extremely low dynamic resistance, typically 0.4 Ohm Packaging,
Pricing and Availability The CM1242-33CP will be available at
$0.035 each at 15,000 units. Engineering samples are available now,
and production is scheduled for 1Q2010. About California Micro
