SP724AHTG is a 4-channel low-capacitance TVS array for ESD protection. Alternatives exist in the same SOT-23-6 package, but require careful verification of pinout and key electrical parameters like capacitance and leakage current.

AI replacement insight

Package riskhigh

Pinout is not verified. Incorrect pinout requires a PCB redesign.

Electrical risklow

Top candidates have comparable or better electrical specs, but leakage current should be checked.

Can it be replaced directly?

Direct replacement for SP724AHTG should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Verify the pinout of SRV05-4HTG-D or TPD4E1U06DBVR for your application.

Main risk

Pinout mismatch is the primary risk, as different 4-channel TVS arrays in SOT-23-6 packages have varying internal connections.
