Transient Voltage Suppressors Array for ESD Protection
ESDXXV55T-4L Series
Description
SOT-553
The ESDXXV55T-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.
