Engineering Selection Recommendations

All identified substitute parts—NRVB30H100MFST1G and NRVB30H100MFST3G—are parametric equivalents to the MBR30H100MFST3G and are suitable for direct substitution in applications requiring a 100 V, 30 A Schottky rectifier diode in a 5-DFN surface mount package.

Selection Basis:

All parts maintain Active product status and are ROHS3 compliant, ensuring regulatory compliance and long-term availability. The electrical characteristics—including reverse voltage rating, average rectified current, forward voltage drop, fast recovery speed, and reverse leakage current—are identical across all three parts. Mechanical compatibility is confirmed through identical package specifications and surface mount mounting type.

The substitute parts differ only in base product number designation (NRVB30 versus MBR30) and packaging tape configuration (MFST1G versus MFST3G), which do not affect electrical performance or functional compatibility in circuit applications.
