Substitute Part Grouping Explanation

Substitution of the V8PM12HM3_A/I is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 120 V
• Current - Average Rectified (Io): 3.6 A
• Voltage - Forward (Vf) (Max) @ If: 840 mV @ 8 A
• Current - Reverse Leakage @ Vr: 300 µA @ 120 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Packaging Specifications:

• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Supplier Device Package: TO-277A (SMPC)

Compliance & Qualification:

• Grade: Automotive
• Qualification: AEC-Q101
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all parameters listed above. Variations in manufacturing batch codes (suffix designations such as _A/I versus _A/H) do not affect electrical or mechanical compatibility when all other specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The V8PM12HM3_A/H is a direct parametric equivalent to the V8PM12HM3_A/I. Both components are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, mechanical packaging, and compliance certifications. The difference in part number suffix (_A/I versus _A/H) reflects manufacturing batch or tape reel configuration only and does not affect component performance or interchangeability.

Both parts carry Active product status and maintain AEC-Q101 automotive qualification, confirming suitability for automotive-grade applications. ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity classification are consistent across both variants, ensuring compatibility with standard surface mount assembly processes and storage conditions.

Selection between V8PM12HM3_A/I and V8PM12HM3_A/H should be based on inventory availability and supply chain requirements. The V8PM12HM3_A/H currently maintains higher inventory levels (6300 Pcs) compared to the V8PM12HM3_A/I (783 Pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are V8PM12HM3_A/I and V8PM12HM3_A/H electrically interchangeable?

A: Yes. Both parts are identical in all electrical specifications including reverse voltage (120 V), average rectified current (3.6 A), forward voltage (840 mV @ 8 A), reverse leakage current (300 µA @ 120 V), and recovery speed (Fast Recovery ≤ 500ns, > 200mA). They are direct substitutes.

Q: Do these parts use the same package and mounting method?

A: Yes. Both V8PM12HM3_A/I and V8PM12HM3_A/H use the TO-277A (SMPC) package with 3-PowerDFN configuration and are mounted as surface mount components. PCB layout and assembly processes are identical.
