Substitute Part Grouping Explanation

Substitute parts for the V40DL45HM3_A/I are identified based on strict parametric equivalence within the Vishay eSMP®/TMBS® Schottky diode family. All substitute parts maintain the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io): 40 A
• Voltage - Forward (Vf) (Max) @ If: 660 mV @ 40 A
• Current - Reverse Leakage @ Vr: 5 mA @ 45 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -40°C to 150°C
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab)
• Mounting Type: Surface Mount
• Technology: Schottky
• Series: eSMP®, TMBS®

All substitute parts share the same base product number (V40DL45) and are manufactured by Vishay General Semiconductor - Diodes Division. Substitution is valid only when all electrical and mechanical parameters remain identical across the component family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V40DL45HM3_A/I, V40DL45-M3/I, and V40DL45BP-M3/I—are direct parametric equivalents within the Vishay eSMP®/TMBS® Schottky diode family. Selection among these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation.

All parts maintain active product status and comply with ROHS3 and REACH regulations. The V40DL45HM3_A/I carries AEC-Q101 automotive qualification. The substitute parts V40DL45-M3/I and V40DL45BP-M3/I specify Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating superior moisture handling characteristics during storage and assembly.

Current inventory levels are as follows: V40DL45HM3_A/I (1094 units), V40DL45-M3/I (1655 units), and V40DL45BP-M3/I (1404 units). Selection should prioritize availability and lead time requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can V40DL45-M3/I be used as a direct replacement for V40DL45HM3_A/I?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (45 V reverse voltage, 40 A average rectified current, 660 mV forward voltage at 40 A) and mechanical compatibility (TO-263-3 D2PAK package, surface mount). Both are manufactured by Vishay and belong to the eSMP®/TMBS® series.

Q: What is the difference between V40DL45BP-M3/I and V40DL45-M3/I?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the designation suffix, which may indicate internal manufacturing or qualification variations within Vishay's product line. Both maintain the same 45 V/40 A ratings and TO-263-3 package.

Q: Are all three parts suitable for automotive applications?

A: The V40DL45HM3_A/I carries explicit AEC-Q101 automotive qualification. The substitute parts V40DL45-M3/I and V40DL45BP-M3/I do not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring AEC-Q101 compliance, the V40DL45HM3_A/I is the specified choice.

Q: What does MSL 1 (Unlimited) mean on the substitute parts?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions during storage and assembly. These parts can be stored and handled without special moisture control measures, providing greater flexibility in supply chain management compared to higher MSL ratings.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, for non-automotive applications. All three parts share identical electrical parameters (45 V reverse voltage, 40 A current rating, 660 mV forward voltage, 5 mA reverse leakage) and the same TO-263-3 D2PAK surface mount package. PCB layouts and thermal management designs require no modification.

Q: What is the base product number, and why is it significant?

A: The base product number is V40DL45. All three parts (V40DL45HM3_A/I, V40DL45-M3/I, V40DL45BP-M3/I) share this base designation, indicating they are variants within the same product family with identical core electrical specifications and performance characteristics.

Q: Are there any compliance or regulatory differences between the three parts?

A: All three parts are ROHS3 compliant and REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080. The primary regulatory distinction is that V40DL45HM3_A/I carries AEC-Q101 automotive qualification, while the substitute parts do not list this certification.
