TVS Diode Arrays
TVS Avalanche Diode in a Chip Scale Package
SP0501BACT
The product is a silicon P/N structure tailored for ESD protection and is
offered in the standard EIA 0402 size. The single channel Chip Scale
device is used to help protect sensitive digital or analog input circuits on
data, signal, or control lines with voltage levels up to 5VDC. The bipolar
device is ideal for protection where AC signals are present.
The state-of-the-art device is designed to suppress ESD and other
transient over-voltage events to meet the International Electrotechnical
Compatability (EMC transient immunity stantards IEC 61000-4-2 for
Electrosatic Discharge Requirements). The monolithic silicon device is
comprised of specially designed structures for transient voltage suppres-
sion (TVS). The size and shape of these structures has been tailored
for transient protection. The low capacitance and clamp voltage are ideal
for high speed signal line protection.
