AOZ8311
410W Peak Power One-line TVS Diode
General Description
Features
The AOZ8311 is a one-line 410W peak power
transient voltage suppressor diode designed to protect
voltage sensitive electronics from high transient
conditions and ESD.

This device incorporates one TVS diode in an ultra-small
1.6 x 0.8mm package. The AOZ8311 is designed for line
protection from high surge transients up to 380W peak
power (8/20µs). It may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4 (±15kV
air, ±8kV contact discharge).

Small package saves board space

Low insertion loss

Peak power: 410W (8/20µs)
The ultra-small 1.6 x 0.8 x 0.5mm 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.
Typical Application
ESD protection for high-speed data lines:
– Exceeds: IEC 61000-4-2 (ESD) ±30kV (air),
±30kV (contact)
– Human Body Model (HBM) ±24kV
