A pin-compatible upgrade with higher surge rating (5A) and lower capacitance (0.3pF).
TPD4S010DQAR is a 4-channel TVS diode for ESD protection in a DFN2510-10 package. Excellent replacements are available, including a pin-compatible upgrade, TPD4E05U06DQAR, and several functional alternatives.
Many alternatives exist in the same DFN2510-10 package, but pinout must be verified.
Some candidates have lower peak current ratings. Capacitance is generally similar or better.
Direct replacement for TPD4S010DQAR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for TPD4S010DQAR, then review parametric alternatives for package and electrical fit.
The main risk when considering other alternatives is a lower peak pulse current (Ipp) rating, which could reduce surge protection effectiveness.
