Engineering Selection Recommendations

Both SE70PGHM3_A/I and SE70PGHM3_A/H are Active product status devices from Vishay General Semiconductor - Diodes Division. Both parts carry identical electrical specifications, mechanical packaging, and regulatory compliance certifications. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

The SE70PGHM3_A/H offers higher inventory availability (5509 pieces) compared to SE70PGHM3_A/I (840 pieces). Both parts maintain AEC-Q101 automotive qualification, ROHS3 compliance, and REACH unaffected status. The difference in part number suffix (_A/H versus _A/I) reflects manufacturing or distribution batch coding and does not indicate functional or electrical variation.

For applications requiring automotive-grade rectification at 400 V and 2.9 A with surface mount TO-277A packaging, either part satisfies the technical requirements identically.
