DESCRIPTION
APPEARANCE
The SLVU2.8K-4U provides 500 Watt protection with LOW CAPACITANCE, LOW
CLAMPING VOLTAGE and the LOWEST LEAKAGE in the industry for two lines to
ground (common mode). Low unidirectional capacitance of 10 pF for each line and low
standby current provides a more stable signal in higher frequency applications and at
lower operating voltages of 2.8 volts. Negative transients on each line are also clamped
to very low voltages with an anti-parallel forward diode in each leg (line to ground). The
SLVU2.8K-4U is designed for use in applications where protection is required at the
board level from voltage transients caused by electrostatic discharge (ESD) as defined in
IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and effects of
secondary lightning. These arrays are used to protect two lines by connecting both pins 1
and 8 to line 1 and pins 4 and 5 to line 2. Pins 2 and 7 as well as pins 3 and 6 are all
connected to ground as shown in Figures 3, 4 and 5.

* Capacitance line-to-ground is 10 pF typical (including anti-parallel diode for negative transients and low clamping voltage).
Note: Transient Voltage Suppressor (TVS) product is normally selected based on its stand off voltage VWM. Product selected
voltage should be equal to or greater than the continuous peak operating voltage of the circuit to be protected.
