Description
CS0801M is a low-capacitance Transient Voltage
Suppressor (TVS) designed to provide electrostatic
discharge (ESD) protection for data, control or power
lines. With typical capacitance of 12pF only, CS0801M is
designed to protect parasitic-sensitive systems against
over-voltage and over-current transient events. It
complies with IEC 61000-4-2 (ESD), Level 4 (±15kV air,
±8kV contact discharge), IEC 61000-4-4 (electrical fast
transient - EFT) (40A, 5/50 ns), very fast charged device
model (CDM) ESD and cable discharge event (CDE), etc.
Circuit Diagram
Pin Configuration
CS0801M uses ultra-small uDFN-2L package. Each
CS0801M device can protect one data line. It offers
system designers flexibility to protect single data line
where space is a premium concern.
