TVS Avalanche Diode Array in a Unipolar Chip Scale Package
SP0504BAC, SP0508BAC, SP0516BAC
NEW
This family of avalanche diode arrays are designed for ESD protection
and offered in an ultra small chip scale package.
The multi-channel devices are used to help protect sensitive digital or
analog input circuits on data, signal, or control lines with unipolar voltage
levels up to 5VDC.
The state-of-the-art structure 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
Electrostatic Discharge Requirements).
The monolithic silicon devices are comprised of specially designed
structures for transient voltage suppression (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.
