Engineering Selection Recommendations

For Active Production and New Designs:

The VS-MBRB3045CTL-M3 and VS-MBRB3045CT-M3 are direct Vishay equivalents with identical electrical and mechanical specifications. Both parts maintain active product status and are ROHS3 compliant with AEC-Q101 automotive qualification. Selection between these two Vishay alternatives depends on packaging requirements: VS-MBRB3045CTL-M3 is supplied in Tape & Reel format, while VS-MBRB3045CT-M3 is supplied in Tube format.

The STPS30L45CG-TR from STMicroelectronics is a manufacturer-recommended cross-reference that meets all mandatory electrical and mechanical parameters. This part is supplied in Tape & Reel packaging and maintains active product status with ROHS3 compliance. The STPS30L45CG-TR exhibits lower forward voltage (550 mV @ 15 A versus 760 mV @ 30 A) and lower reverse leakage current (400 µA @ 45 V versus 1 mA @ 45 V), which may provide thermal and efficiency benefits in specific applications.

For Repair and Legacy System Support:

Existing inventory of VS-MBRB3045CTTRLP may be supplemented with any of the three substitute parts listed above. All substitute parts are electrically and mechanically compatible with the original design.
