Best Alternatives to MBRS1100T3G

Package: DO-214AA, SMBonsemiDiodes - Rectifiers - SinglePackage: Tape & Reel (TR); Cut Tape (CT); Digi-Reel®Voltage - DC Reverse (Vr) (Max): 100 VCurrent - Average Rectified (Io): 1AVoltage - Forward (Vf) (Max) @ If: 750 mV @ 1 ACurrent - Reverse Leakage @ Vr: 500 µA @ 100 V

MBRS1100T3G is a 100V, 1A Schottky rectifier in an SMB package. When seeking alternatives, prioritize matching the Schottky technology for low forward voltage and fast switching, along with the SMB package for board compatibility.

AI replacement insight

Electrical riskmedium

Using a non-Schottky diode will increase power loss. The best match has no voltage margin.

Package risklow

The SMB package is standard and widely available.

Sourcing risklow

Multiple vendors produce similar diodes in this package.

Can it be replaced directly?

Direct replacement for MBRS1100T3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

STPS2H100U is the best path, offering a Schottky diode in the same package with improved current and forward voltage. However, its 100V rating provides no safety margin over the target.

Main risk

The main risk is substituting with an 'Ultrafast' diode instead of a 'Schottky' type, which will significantly increase power dissipation due to higher forward voltage.
