UN ESD12V26T-4L Transient voltage suppressors array for esd protection Datasheet

Transient Voltage Suppressors Array for ESD Protection
ESDXXV26T-4L Series
Description
SOT-26
The ESDXXV26T-4L is designed to protect voltage sensitive
components from ESD and transient voltage events. Excellent
clamping capability, low leakage, and fast response time,
make these parts ideal for ESD protection on designs where
board space is at a premium.
