MMDL914T1G is a high-speed switching diode from onsemi in a SOD-323 package. Finding a direct replacement requires carefully matching its 4ns reverse recovery time, a critical parameter for high-frequency applications that is not met by most common alternatives.

AI replacement insight

Electrical riskhigh

Slower trr (switching speed) can cause timing issues, increased power loss, and circuit failure.

Package risklow

All candidates match the SOD-323 package, ensuring form and fit compatibility.

Sourcing riskmedium

While many alternatives exist, none are a true functional match, complicating the sourcing process.

Can it be replaced directly?

No direct drop-in replacement has been identified. All potential alternatives have a significantly slower switching speed (35-50ns vs the target's 4ns), which poses a high electrical risk in fast switching circuits.

Best replacement path

Evaluate onsemi's BAS20HT1G. It shares the same package and manufacturer, but requires thorough testing to ensure the slower 50ns switching speed is acceptable for the specific application.

Main risk

The primary risk is circuit malfunction or failure due to the much slower reverse recovery time (trr) of all potential alternatives.
