TPD4E05U06DQAR is a close 4-line 5V low-cap TVS candidate.
ULC0524P is a 5V ultra-low-capacitance 4-line TVS array. Similar parts exist, but pinout and surge data need FAE review.
Clamp, Ipp, and ESD vary.
Package text alone is not pinout proof.
Passive protection device.
Some records have vendor conflicts.
Direct replacement for ULC0524P should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with TPD4E05U06DQAR, then ULC0544P10, and verify pinout and clamp data.
Pinout and ESD/surge ratings are not fully verified.
