V3PAL45HM3_A/I Equivalent & Substitute Parts

Part Overview

The V3PAL45HM3_A/I is an active Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 45 V DC reverse voltage with 3 A average rectified current capacity and is housed in a DO-221BC (SMPA) package. The device is qualified to AEC-Q101 automotive standards and complies with ROHS3 and REACH regulations. Substitute parts are identified when electrical characteristics, mechanical packaging, and compliance certifications remain equivalent across the component lifecycle and manufacturing variations.

Substitution of the V3PAL45HM3_A/I is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 540 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 450 µA @ 45 V

Mechanical Equivalence Criteria:

• Package / Case: DO-221BC, SMA Flat Leads Exposed Pad
• Mounting Type: Surface Mount
• Supplier Device Package: DO-221BC (SMPA)

Compliance & Qualification Criteria:

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

The substitute part V3PAL45-M3/I meets all electrical, mechanical, and compliance requirements and shares the same base product number (V3PAL45), confirming parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the V3PAL45HM3_A/I and V3PAL45-M3/I are active products manufactured by Vishay General Semiconductor - Diodes Division. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation.

V3PAL45HM3_A/I is designated as part of the TMBS® series and carries explicit automotive grade classification with AEC-Q101 qualification. This part number is suitable for applications requiring documented series designation and explicit automotive qualification traceability.

V3PAL45-M3/I provides equivalent electrical performance and mechanical compatibility with identical compliance certifications (ROHS3, REACH Unaffected, AEC-Q101 automotive grade). This part number is suitable for applications where series designation is not a critical specification requirement.

Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating compatibility with standard surface mount assembly processes without special moisture control requirements.

Frequently Asked Questions (FAQ)

Q: Can V3PAL45-M3/I be used as a direct replacement for V3PAL45HM3_A/I?

A: Yes. Both parts are parametrically equivalent across all electrical characteristics (45 V reverse voltage, 3 A average rectified current, 540 mV forward voltage at 3 A, fast recovery speed, and 450 µA reverse leakage). Both use identical DO-221BC (SMPA) surface mount packaging and share the same base product number (V3PAL45). Compliance certifications are equivalent (ROHS3, REACH Unaffected, AEC-Q101 automotive grade).

Q: Are there differences in the TMBS® series designation?

A: The V3PAL45HM3_A/I is explicitly designated as part of the TMBS® series. The V3PAL45-M3/I does not carry this series designation in the provided specifications. Both parts meet identical electrical and mechanical requirements. Series designation does not affect functional equivalence.

Q: What is the significance of the part number suffix differences?

A: The V3PAL45HM3_A/I includes the suffix "HM3_A/I" while V3PAL45-M3/I uses the suffix "-M3/I". Both suffixes indicate surface mount packaging variants of the base product V3PAL45. The differences reflect manufacturing or distribution channel variations rather than electrical or mechanical specification changes.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry automotive grade classification and AEC-Q101 qualification. Operating temperature range is -40°C to 150°C junction temperature for both parts, meeting automotive thermal requirements.

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

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity level. This classification indicates no special moisture control or baking procedures are required prior to surface mount assembly. Standard handling and storage practices are sufficient.

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

A: Yes. Electrical performance, mechanical packaging (DO-221BC SMPA), mounting type (surface mount), and compliance certifications are identical. No design modifications are required for substitution.

Q: What is the reverse leakage current specification?

A: Both parts specify 450 µA maximum reverse leakage current at 45 V reverse voltage. This parameter is identical across both part numbers.

Q: Are there any differences in forward voltage characteristics?

A: No. Both parts specify 540 mV maximum forward voltage at 3 A forward current. Forward voltage characteristics are identical.
