1 Lines, Bi-directional, Low Capacitance
Transient Voltage Suppressors
The SPD9108W is a low capacitance TVS (Transient Voltage
Suppressor) array designed to protect high speed data
interfaces. It has been specifically designed to protect
sensitive electronic components which are connected to data
and transmission lines from over-stress caused by
Electrostatic Discharge (ESD), cable discharge events (CDE),
lightning and other induced voltage surges.
The SPD9108W incorporates low capacitance steering
diodes that reduce the typical capacitance to 1.2pF per line.
The SPD9108W may be used to provide ESD protection up
to ±30kV (contact discharge) according to IEC61000-4-2,
and withstand peak pulse current up to 18A (8/20μs)
according to IEC61000-4-5.
The SPD9108W is available in SOD-323 package. Standard
products are Pb-free and Halogen-free.
Stand-off voltage: 8V Max.
Transient protection for each line according to
IEC61000-4-2 (ESD): ±30kV (contact discharge)
IEC61000-4-4 (EFT): 40A - 5/50ns
IEC61000-4-5 (surge): 18A (8/20μs).
Low capacitance: CJ = 1.2pF typ.
Ultra-low leakage current: IR = 1nA typ.
Low clamping voltage.
