Substitute Part Grouping Explanation

Substitution for the G3S06503C has been determined strictly according to core electrical and mechanical performance criteria. The allowed parameters for equivalent replacement include: technology (SiC Schottky), maximum DC reverse voltage (650 V), average rectified current rating (11.5A), forward voltage drop at specified test current, reverse recovery time (0 ns), reverse leakage current, capacitance value, mounting type (surface mount), industry-standard package/case (TO-252-3, DPAK), junction temperature range, and moisture sensitivity level. Only parts matching these parameters are considered equivalent within the Diodes, Rectifiers category.

Engineering Selection Recommendations

Both G3S06503C and G3S06504C are listed as active, with inventory available in new original condition. Compliance status (REACH info available upon request) and export classification (ECCN: EAR99, HTSUS: 8541.10.0080) are consistent for both parts. The moisture sensitivity level is 1 (unlimited), suitable for standard storage and handling requirements. Selection between these models may be determined by packaging preference (Cut Tape vs Bulk) or procurement availability. No specification provided necessitates exclusion of either part as a functional substitute.

Frequently Asked Questions (FAQ)

Q: What are the main criteria for selecting substitute SiC Schottky diodes in TO-252 package?
A: Substitution is determined by matching technology, maximum DC reverse voltage, average rectified current, forward voltage characteristics, reverse recovery time, reverse leakage current, capacitance, package type, mounting configuration, operating temperature range, and compliance status.

Q: Are G3S06503C and G3S06504C identical in electrical performance?
