AOZ8811-03
Ultra-Low Capacitance One-line TVS Diode
General Description
The AOZ8811-03 is a ultra-low capacitance one-line
transient voltage suppressor diode designed to protect
very high-speed data lines and voltage sensitive
electronics from high transient conditions and ESD.
This device incorporates one TVS
diode in an ultra-small
DFN 1.0 x 0.6 package. During transient conditions, the
ultra-low capacitance one-line TVS
diode directs the
transient to ground. It may be used to
meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±15kV contact discharge).
The AOZ8811-03 comes in an RoHS compliant DFN
package and is rated over a -40°C to +85°C ambient
temperature range.
The ultra-small DFN 1.0 x 0.6 x 0.4mm package makes it
ideal for applications where PCB space is a premium.
The small size and high ESD protection makes it ideal for
protecting voltage sensitive electronics from high
transient conditions and ESD.
Features
ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±20V (air),
±20kV (contact)
– Human Body Model (HBM) ±15kV
Small package saves board space
Ultra-low capacitance: 0.5pF
Low clamping voltage
Low operating voltage: 3.6V
