Is there a pin-compatible replacement for ES2G?

Yes, several diodes like ES3JA and ES2J use the same DO-214AC (SMA) package and are pin-compatible. However, you must verify all critical electrical parameters before substitution.

What risks should I check before replacing ES2G?

The main risk is using a diode with a slower reverse recovery time (Trr > 35ns), which can cause inefficiency or failure in fast-switching circuits. Always ensure voltage and current ratings are equal or greater than the original.

ES2G Alternatives, Datasheet & Cross Reference | Diotec Semiconductor

Finding a substitute for the ES2G fast recovery diode requires matching its 400V, 2A, and 35ns performance in a DO-214AC (SMA) package. Key alternatives offer upgraded voltage or current, but verifying reverse recovery time is critical for application success.

AI replacement insight

Electrical riskmedium

Reverse recovery time (Trr) is critical and must be verified. Slower parts will cause issues.

Package risklow

The DO-214AC (SMA) package is highly standardized, ensuring mechanical compatibility.

Sourcing risklow

This is a common diode type with multiple manufacturers and available alternatives.

Can it be replaced directly?

Yes, ES3JA is a strong candidate for direct replacement, offering superior voltage and current ratings with no downgrade in performance.

Best replacement path

ES3JA is the recommended upgrade path due to superior electrical ratings and matching critical parameters.

Main risk

The primary risk is substituting with a slower diode (higher Trr), which is a common issue with similarly named parts.

Recommended alternatives

An excellent upgrade with higher voltage (600V) and current (3A) in the same SMA package and 35ns speed.
