TVS Diode Arrays
Lightning Surge Protection - SPLV2.8 Series
Low capacitance protection of a high-speed data pair is
realized by connecting two devices in antiparallel. As shown,
pin 1 of the first device is connected to D1 and pin 2 is
connected to D2. Additionally, pin 2 of the second device is
connected to D1 and pin 1 is connected to D2. Pin 3 must be
NC (or not connected) for both devices. When the potential
on D1 exceeds the potential on D2 (by the rated standoff
voltage), pin 2 on the second device will steer current into
pin 1. The compensating diode will conduct in the forward
direction steering current into the avalanching TVS diode
which is operating in the reverse direction. For the opposite
transient, the first device will behave in the same manner. In
this two device arrangement, the total loading capacitance is
two times the rated capacitance from pin 2 to pin 1 which will
typically be much less than 10pF making it suitable for high-
speed data pair such as 10/100/1000 Ethernet.
Protection of one unidirectional data line is realized by
connecting pin 3 to the protected line, and pins 1 and 2 to
GND. In this configuration, the device presents a maximum
loading capacitance of tens of picofarads. During positive
transients, the internal TVS diode will conduct and steer
current from pin 3 to 1 (GND), clamping the data line at or
below the specified voltages for the device (see Electrical
Characteristics section). For negative transients, the internal
compensating diode is forward biased, steering the current
from pin 2 (GND) to 3.
