CM1214
PRELIMINARY
Application Information
The CM1214-01ST/SO and the CM1214-01DF/DE
protect a single bipolar signal line, such as is found in
RF circuits. One I/O pin (pin 1 for example) is con-
nected to the signal line to be protected, and the other
I/O pin is tied to GND. It is important to have a solid
ground connection in order to reduce the clamping volt-
age. Pin 3 of the 3-lead SOT23 (Pin 1 of the 3-lead
DFN) must be left open (not connected on the PCB).
The CM1214-02MS/MR protects two bipolar lines,
such as for Gbit Ethernet. The PCB traces underneath
the package connect across to the corresponding pins,
i.e., pin 1 to pin 8 etc.
Any disturbance on the line above or below the stand-
off voltage is clamped.
