AI replacement insight
Electrical risklow
When using an upgraded part like NUP2105LT1G. Risk is high if using a downgraded part.
Package riskmedium
SOT-23 pinouts can vary between manufacturers. Pinout verification is always required.
Sourcing risklow
This type of TVS diode is a commodity part with many available suppliers.
Can it be replaced directly?
Direct replacement for PESD1CAN should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The onsemi NUP2105LT1G is the most promising path, offering an upgrade in power and current handling in the same package.
Main risk
The primary risk is using a substitute with a lower peak current (Ipp) rating, which could lead to device failure under surge conditions.
