Best Alternatives to BAT54HT1G

Package: SC-76, SOD-323onsemiDiodes - Rectifiers - SinglePackage: BulkVoltage - DC Reverse (Vr) (Max): 30 VCurrent - Average Rectified (Io): 200mAVoltage - Forward (Vf) (Max) @ If: 800 mV @ 100 mACurrent - Reverse Leakage @ Vr: 2 µA @ 25 V

The BAT54HT1G is a 30V, 200mA Schottky diode in a compact SOD-323 package, valued for its fast switching and low forward voltage. Finding a substitute requires matching these key electrical parameters and package.

AI replacement insight

Electrical riskhigh

Mismatch in forward voltage or capacitance can cause circuit failure or reduced performance.

Package risklow

SOD-323 is a standard package, making physical replacement straightforward.

Sourcing risklow

BAT54 series and similar parts are widely available from multiple manufacturers.

Can it be replaced directly?

LBAT54HT1G appears to be a very close functional match. Other parts like BAT54JFILM offer higher ratings but with a trade-off in higher forward voltage.

Best replacement path

The most direct path is finding another Schottky diode in a SOD-323 package with V_R ≥ 30V and I_F ≥ 200mA, paying close attention to matching the low forward voltage.

Main risk

The primary risk is substituting with a part that has a higher forward voltage (VF), which will increase power dissipation and reduce efficiency, especially in low-power applications.
