Strong alternative with much lower capacitance, but slightly weaker contact ESD protection.
ESDU5V0H4 is a 4-channel, 5V TVS diode array in a SOT23-6 package for high-speed line protection. Key alternatives exist with the same package but have variations in I/O capacitance and ESD ratings that require careful review.
Capacitance and ESD rating differences require circuit-level validation.
All viable candidates share the SOT23-6 package, but pinout must be verified.
Direct replacement for ESDU5V0H4 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
AZC099-04S offers an upgrade in capacitance but a slight downgrade in ESD protection, representing the best functional trade-off.
Mismatched I/O capacitance affecting high-speed signal integrity, or reduced ESD protection compromising system robustness.
