Strong parametric match in SOD-323 package, but bidirectional polarity requires verification before use.
Finding a substitute for the PESD5V0S1BA-N TVS diode requires matching its 5V bidirectional protection in a SOD-323 package. Key alternatives exist, but require careful verification of polarity and current ratings.
Candidates have unverified polarity or missing current ratings, which is critical for protection circuits.
Top candidates use the same SOD-323 package, minimizing layout changes.
Availability of alternatives should be confirmed with distributors.
No verified direct replacement is available. UDD32C05L01 is the closest candidate but requires engineering review to confirm its polarity.
UDD32C05L01, pending verification of its bidirectional polarity from the datasheet.
Polarity mismatch. Using a unidirectional diode instead of a bidirectional one will leave the circuit unprotected in one direction.

| Feature / factor | PESD5V0S1BA-N | UDD32C05L01 | H5VSD3B | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOD-323 | SOD-323 | - | SOD-323 — Same package and pin count. | |
| Voltage | 5.0V | 5.0V | - | 5.0V — Reverse standoff voltage matches. | |
| Power | 350.0W | 350.0W | - | 500.0W — Higher power rating is a safe upgrade. | |
| Current | 17.0A | 17.0A | - | Missing — Peak pulse current (Ipp) must be verified. | |
| Polarity | Bidirectional | Unknown | - | Bidirectional — Summary states bidirectional, matching target. |
UDD32C05L01 by Yageo is a strong parametric match, but its bidirectional polarity must be confirmed. H5VSD3B is another option with higher power, but its current rating needs verification.
