What risks should I check before replacing MURS320T3G?

Key risks include increased power loss and heat from a higher forward voltage (Vf), and potentially degraded performance in high-frequency circuits from a slower reverse recovery time (trr). Always verify these against your application's needs.

MURS320T3G Alternatives, Datasheet & Cross Reference | onsemi

MURS320T3G is a 200V, 3A ultrafast rectifier in an SMC package, often used in automotive applications. Its key performance features are a very fast 35ns recovery time and a low forward voltage of 0.875V for high efficiency.

AI replacement insight

Electrical riskmedium

Higher forward voltage will increase conduction losses. Slower recovery time in some parts can affect switching efficiency.

Package risklow

All recommended candidates use the same SMC package, ensuring mechanical compatibility.

Can it be replaced directly?

Direct replacement for MURS320T3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

ES5GC is the best path for speed-critical applications, while MURS360T3G is a conservative choice from the same manufacturer.

Main risk

Increased power dissipation and thermal stress due to higher forward voltage in all suitable alternatives.

Recommended alternatives

Strong alternative with matching package and speed, plus higher voltage/current. Higher forward voltage is the key trade-off.
