Substitute Part Grouping Explanation

Substitution of the V12P12HM3_A/I is determined by equivalence across the following critical parameters:

• Voltage Rating: 120 V DC reverse voltage (Vr)
• Current Rating: 3.9 A average rectified current (Io)
• Forward Voltage Characteristic: 830 mV maximum at 10 A forward current
• Reverse Leakage: 400 µA at 120 V
• Recovery Speed: Fast recovery ≤ 500 ns for currents > 200 mA
• Package Type: TO-277A (SMPC) surface mount configuration
• Automotive Qualification: AEC-Q101 certification
• Temperature Range: -40°C to 150°C junction operating temperature
• Compliance: ROHS3 compliant, REACH unaffected

The substitute part V12P12HM3_A/H maintains identical electrical specifications and automotive qualification. The primary distinction is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) and Digi-Reel® format. Both parts share the same base product number (V12P12) and series designation (eSMP®, TMBS®).

Parameter Comparison

Engineering Selection Recommendations

Both the V12P12HM3_A/I and V12P12HM3_A/H are active, automotive-qualified products from Vishay General Semiconductor - Diodes Division. Selection between these parts is based on packaging and supply chain requirements rather than electrical performance.

V12P12HM3_A/I is specified when Tape & Reel (TR) packaging is required for automated assembly processes utilizing standard reel-fed pick-and-place equipment.

V12P12HM3_A/H is specified when Cut Tape (CT) or Digi-Reel® packaging is required for lower-volume applications, manual assembly, or alternative feeder systems.

Both parts maintain full compliance with AEC-Q101 automotive qualification, ROHS3 environmental standards, and REACH regulatory requirements. The identical electrical specifications, thermal operating range, and reverse leakage characteristics ensure direct functional interchangeability in circuit applications. Selection does not require electrical re-qualification or circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can V12P12HM3_A/H be used as a direct replacement for V12P12HM3_A/I in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape/Digi-Reel). Direct substitution is valid provided the assembly process can accommodate the alternate packaging format.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical specifications for voltage rating (120 V), current rating (3.9 A), forward voltage (830 mV @ 10 A), reverse leakage (400 µA @ 120 V), and recovery speed (≤ 500 ns). Operating temperature range and thermal characteristics are identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both V12P12HM3_A/I and V12P12HM3_A/H carry AEC-Q101 automotive qualification and are classified as automotive-grade components. Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated high-speed pick-and-place assembly. Cut Tape (CT) and Digi-Reel® packaging provide components in shorter tape lengths or alternative reel formats, typically used for lower-volume production or manual assembly processes.

Q: Can these parts be mixed in the same production run?

A: Mixing packaging formats within a single production run requires process validation to ensure compatibility with the assembly equipment and feeder systems in use. Consult manufacturing process documentation and equipment specifications.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling and storage practices for surface mount components apply.

Q: Are there inventory considerations when selecting between these parts?

A: Yes. The V12P12HM3_A/I is available with 856 pieces in stock, while the V12P12HM3_A/H has 16,600 pieces in stock. Availability may influence selection for time-sensitive applications.
