ESD5311XZ
TECH PUBLIC
Needs validationlow risk
A very strong alternative with identical package, voltage, capacitance, and slightly better air ESD immunity.
Best Alternatives to TPESD5311Z
Finding a replacement for the TPESD5311Z TVS diode involves matching its 5V rating, ultra-low 0.28pF capacitance, and DFN0603-2 package. Several strong alternatives and upgrades exist from the same manufacturer.
AI replacement insight
Package risklow
All strong candidates use the same DFN0603-2 package, but pinout should always be confirmed.
Electrical riskmedium
Ensure the candidate's ESD rating and capacitance meet or exceed the original's requirements for your application.
Can it be replaced directly?
Direct replacement for TPESD5311Z should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use TPAZ5B65-01F or TPESD0516Z as an upgrade for better ESD protection and/or lower capacitance.
Main risk
The main risk is substituting with a part that has weaker ESD protection, like TPESD8472MUT5G, which could compromise circuit reliability.
