SL Connection Options
Device Connection for Protection of One High-Speed
Data Line
The SL series devices are designed to protect high-
speed data lines. The SLxx utilizes a low capacitance
compensation diode in series with, but in opposite
polarity to a TVS diode in each line to achieve an
effective capacitance of less than 5pF per device.
During a transient event, the internal rectifier must be
forward biased (TVS is reversed biased). Therefore,
each device will only suppress transient events in one
polarity. To achieve protection in both positive and
negative polarity, a second device is connected in anti-
parallel to the first. On unidirectional lines, a fast
switching steering diode may be used as an alternative
to using two SL devices.
The options for connecting the devices are as follows:
Low capacitance protection of one high-speed
line: Protection of one unidirectional or bidirec-
tional high-speed line is achieved by connecting two
devices in anti-parallel. Pin 1 of the first device is
connected to the line and pin 2 is connected to
ground (or to a second line for differential protec-
tion). Pin 2 of the second device is connected to
line 1 and pin 1 is connected to ground (or line 2)
as shown. Pin 3 is not connected. During positive
duration transients, the first device will conduct
from pin 1 to 2. The steering diode conducts in the
forward direction while the TVS will avalanche and
conduct in the reverse direction. During negative
transients, the second device will conduct in the
same manner. For optimum protection, the ground
connections should be made directly to the ground
plane for best results. The path length is kept as
short as possible to reduce the effects of parasitic
inductance in the board traces. The path length
between the TVS and the protected line should
also be minimized.
Connection Option for Unidirectional Lines Only:
An optional method for protecting unidirectional
(normal signal polarities above ground) lines is to
add a fast switching steering diode in parallel to the
SL TVS. Input/outputs are connected to pin 1 of
the SL device and the cathode of the rectifier. The
anode of the diode and pin 2 of the SL TVS are
connected to ground.

Applications Information
Matte Tin Lead Finish
Matte tin has become the industry standard lead-free
replacement for SnPb lead finishes. A matte tin finish
is composed of 100% tin solder with large grains.
Since the solder volume on the leads is small com-
pared to the solder paste volume that is placed on the
land pattern of the PCB, the reflow profile will be
determined by the requirements of the solder paste.
Therefore, these devices are compatible with both
lead-free and SnPb assembly techniques. In addition,
unlike other lead-free compositions, matte tin does not
have any added alloys that can cause degradation of
the solder joint.
