ES3J is a 600V, 3A fast recovery rectifier in a DO-214AB (SMC) package. Key alternatives include parts with higher current ratings like ES8JC (8A) and ES10J (10A) that match the critical 35ns recovery time.

AI replacement insight

Electrical riskhigh

Using a standard diode instead of fast recovery will likely cause circuit failure.

Package risklow

The DO-214AB (SMC) package is a common industry standard.

Can it be replaced directly?

ES8JC is a strong candidate for replacing ES3J. It matches the package, voltage, and fast recovery time, while offering a higher current rating of 8A.

Best replacement path

Upgrade to a higher current part like ES8JC (8A) or ES10J (10A) which are readily available.

Main risk

The primary risk is substituting with a standard recovery diode instead of a fast recovery one. Ensure any replacement has a reverse recovery time (trr) of approximately 35ns.
