Transient Voltage Suppressors Array for ESD Protection Low

Transient Voltage Suppressors Array for ESD Protection
Low Capacitance
SLVU2.8
Description
SOT-23
The SLVU2.8 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.
