Silicon Protection Circuits
TVS Avalanche Diode Array in a Bipolar Chip Scale Package
SP0504BBC, SP0508BBC, SP0516BBC
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 Bipolar voltage levels up to 5VDC.
The array is ideal for protection when AC signals are present.
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.
