General Description

The AOZ8621UNI is a series of 1-channel unidirectional

high surge transient voltage suppressors designed to

protect power rails such as battery and VBUS from damaging

ESD or surge events. The VRWM range is from 5V

to 22V.

This device consists a unidirectional TVS diode in a single

package. During transient events, the diode directs

the transient to either the positive side of the power supply

line or to ground.

The AOZ8621UNI provides low clamping voltage making

it ideally suited for power rail protection in mobile and

computing devices.

The AOZ8621UNI comes in a RoHS compliant and Halogen

Free 2mm×2mm×0.55mm package and is rated for -

40°C to +125°C junction temperature range.
