Transient Voltage Suppressors for ESD Protection

Transient Voltage Suppressors for ESD Protection
ESDXXV52D-C Series
Description
SOD-523
The ESDXXV52D-C 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.
