NSR0240V2T1G is a high-performance 40V, 250mA Schottky diode in a SOD-523 package, optimized for low forward voltage and low leakage. Finding a direct drop-in replacement is challenging due to its specialized characteristics.

AI replacement insight

Electrical riskmedium

Higher VF, IR, and CT in all candidates will impact performance.

Package risklow

All viable candidates use the same SOD-523 package.

Can it be replaced directly?

No direct, fully equivalent replacement has been identified. Alternatives in the same package have higher electrical losses.

Best replacement path

Select a candidate like SD103AWT and verify its higher electrical losses (VF, IR) and capacitance (CT) are acceptable for your circuit.

Main risk

The main risk is increased power loss and signal degradation due to higher forward voltage, leakage, and capacitance in all available alternatives.
