Best Alternatives to MBRS130LT3G

Package: DO-214AA, SMBonsemiDiodes - Rectifiers - SinglePackage: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Product Status: ActiveVoltage - DC Reverse (Vr) (Max): 30 VCurrent - Average Rectified (Io): 2AVoltage - Forward (Vf) (Max) @ If: 445 mV @ 2 A

MBRS130LT3G is a 30V, 2A Schottky rectifier in an SMB package from onsemi, valued for its low forward voltage and efficiency. When seeking alternatives, prioritize matching the Schottky technology and low Vf for optimal performance.

AI replacement insight

Electrical riskmedium

Key parameters like forward voltage (Vf) and reverse leakage (Ir) can differ, impacting efficiency and thermal performance.

Package risklow

The SMB package is standardized, but slight dimensional differences between manufacturers should be checked against the PCB layout.

Can it be replaced directly?

Direct replacement for MBRS130LT3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

STPS5L60U from STMicroelectronics offers upgraded voltage/current ratings in the same package with a comparable forward voltage.

Main risk

The primary risk when substituting a Schottky diode is increased power dissipation and heat if the replacement has a higher forward voltage (Vf).
