Substitute Part Grouping Explanation

Substitute parts for the MBR8H100MFST3G are determined by electrical and mechanical parameter equivalence. All substitute parts must satisfy the following criteria:

Critical Substitution Parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 8 A
Voltage - Forward (Vf) (Max) @ If: 900 mV @ 8 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 2 µA @ 100 V
Mounting Type: Surface Mount
Package / Case: 8-PowerTDFN, 5 Leads
Supplier Device Package: 5-DFN (5x6) (8-SOFL)
Operating Temperature - Junction: -55°C ~ 175°C
Technology: Schottky
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements. Packaging format variations (Tape & Reel, Cut Tape & Digi-Reel) do not affect functional equivalence. Automotive-grade variants with AEC-Q101 qualification represent enhanced reliability options within the substitution group.
