ES2JF is a 600V, 2A super fast recovery rectifier in a compact SMAF package, ideal for high-frequency power applications. Finding a direct drop-in is challenging, but functional alternatives exist with similar performance in different packages.

AI replacement insight

Electrical riskhigh

Reverse recovery time (trr) is critical and hard to match.

Package riskhigh

Best functional matches are in different packages, requiring board changes.

Can it be replaced directly?

No direct drop-in replacement with matching performance is readily available. Candidates in the same package have significantly worse recovery times.

Best replacement path

Functional alternate (e.g., ES10J, ES2M) requiring PCB redesign.

Main risk

The primary risk is substituting with a diode that has a slower reverse recovery time (trr), which can cause failure in high-frequency circuits.
