Needs validationmedium risk
Similar Nexperia part in SOT23 with matching 24V rating, but has higher clamping voltage and is NRND.
Best Alternatives to PESD2IVN24-TR
PESD2IVN24-TR is an automotive TVS diode with excellent low clamping voltage for CAN bus protection. Finding a direct, drop-in replacement is challenging, as most alternatives offer weaker clamping performance and require careful validation.
AI replacement insight
Electrical riskhigh
Most alternatives have a higher clamping voltage (40V+ vs 33V), offering weaker protection.
Package risklow
SOT-23 is a standard package, and several alternatives share the same form factor.
Sourcing riskmedium
While alternatives exist, finding one that matches the low clamping voltage is difficult.
Can it be replaced directly?
No drop-in replacement was found. All potential alternatives require careful engineering review, especially for clamping voltage.
Best replacement path
SZNUP2105LT1G from onsemi is an active alternative with higher power ratings, but its clamping voltage is higher and must be verified for system compatibility.
Main risk
The primary risk is the higher clamping voltage of alternatives, which may not provide sufficient protection for sensitive CAN transceivers.
