Substitute Part Grouping Explanation

Substitution of the V12P8HM3_A/I is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Reverse voltage rating: 80 V
• Average rectified current: 12 A
• Forward voltage drop: 660 mV @ 12 A
• Reverse leakage current: 1 mA @ 80 V
• Recovery speed classification: Fast Recovery ≤ 500ns, > 200mA

Mechanical & Package Specifications:

• Package type: TO-277, 3-PowerDFN
• Mounting configuration: Surface Mount
• Supplier device package: TO-277A (SMPC)

Compliance & Certification:

• Technology: Schottky
• Automotive grade designation
• AEC-Q101 qualification
• ROHS3 compliance
• REACH unaffected status

The substitute part V12P8HM3_A/H maintains identical electrical performance and mechanical compatibility while differing only in packaging configuration (Tape & Reel variant with MSL 1 rating).

Parameter Comparison

Engineering Selection Recommendations

Both the V12P8HM3_A/I and V12P8HM3_A/H are active production parts from Vishay General Semiconductor - Diodes Division with full AEC-Q101 automotive qualification. Selection between these parts is based on supply chain availability and packaging configuration requirements rather than electrical or mechanical performance differences.

The V12P8HM3_A/I is suitable for applications requiring the specified packaging variant with current inventory of 941 pieces. The V12P8HM3_A/H provides an alternative with higher inventory availability (7007 pieces) and includes MSL 1 (Unlimited) moisture sensitivity rating, indicating enhanced storage stability characteristics.

Both parts maintain identical electrical performance across all specified parameters: 80V reverse voltage, 12A average rectified current, 660 mV forward voltage drop, and fast recovery characteristics. Mechanical compatibility is confirmed through identical TO-277A (SMPC) package specifications and surface mount configuration.

Compliance certifications are equivalent: ROHS3 compliance, REACH unaffected status, and AEC-Q101 automotive qualification are maintained across both part numbers. Operating temperature range remains -40°C to 150°C junction temperature for both variants.
