TVS Avalanche Diode Array in a Unipolar Chip Scale Package

SP0504BAC, SP0508BAC, SP0516BAC

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.
