SMP3003-TL-1E Equivalent & Substitute Parts

Part Overview

The SMP3003-TL-1E is a P-Channel MOSFET manufactured by onsemi, rated for 75V drain-to-source voltage and 100A continuous drain current in a surface mount TO-263 (D2PAK) package. This device is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity. Substitute parts must maintain functional compatibility across critical electrical parameters including voltage rating, current capacity, and thermal characteristics while accommodating the surface mount package format.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMP3003-TL-1E are identified based on the following critical parameters that determine functional equivalence:

Mandatory Compatibility Criteria:

• FET Type: P-Channel topology
• Technology: MOSFET (Metal Oxide)
• Mounting Type: Surface Mount
• Package Format: TO-263 family (D2PAK, TO-263AA, TO-263AB)
• Drain-to-Source Voltage (Vdss): Equal to or greater than 75V
• Continuous Drain Current (Id): Equal to or greater than 100A
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The IXTA120P065T qualifies as a substitute based on these criteria. Although its Vdss rating of 65V is lower than the SMP3003-TL-1E, it exceeds the continuous drain current requirement at 120A and maintains compatible package geometry, surface mount configuration, and regulatory compliance. The lower voltage rating restricts its use to applications where the maximum operating voltage does not exceed 65V.

Parameter Comparison

Engineering Selection Recommendations

IXTA120P065T as Substitute for SMP3003-TL-1E:

The IXTA120P065T is an active product with confirmed availability (89,640 pieces in stock) and meets all mandatory compatibility requirements. Both devices are ROHS3 compliant, MSL 1 rated, and housed in compatible TO-263 surface mount packages.

Application Scope Limitation:

The IXTA120P065T has a Vdss rating of 65V compared to the SMP3003-TL-1E's 75V rating. This substitution is valid only for applications where the maximum drain-to-source voltage does not exceed 65V. Applications requiring the full 75V voltage capability cannot use this substitute without circuit redesign.

Performance Advantages:

The IXTA120P065T provides superior continuous drain current (120A versus 100A), lower gate charge (185 nC versus 280 nC), and significantly higher power dissipation capability (298W versus 90W). These characteristics enable improved thermal performance and faster switching characteristics in compatible applications.

Regulatory and Supply Considerations:

Both devices maintain equivalent regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification). The IXTA120P065T's active product status and substantial inventory ensure long-term supply availability, addressing the obsolescence of the SMP3003-TL-1E.

Frequently Asked Questions (FAQ)

Q: Can the IXTA120P065T replace the SMP3003-TL-1E in all applications?

A: No. The IXTA120P065T has a maximum Vdss of 65V, while the SMP3003-TL-1E is rated for 75V. Substitution is valid only when the circuit's maximum drain-to-source voltage does not exceed 65V. Applications requiring higher voltage operation require alternative components or circuit modification.

Q: Are the packages physically compatible?

A: Yes. Both devices use the TO-263 (D2PAK) surface mount package with identical pin configuration (2 leads + tab). PCB layouts and thermal management designs require no modification for package compatibility.

Q: What are the key differences in electrical performance?

A: The IXTA120P065T offers higher continuous drain current (120A versus 100A), lower gate charge (185 nC versus 280 nC), and substantially higher power dissipation (298W versus 90W). The SMP3003-TL-1E provides higher voltage capability (75V versus 65V). On-resistance specifications differ in test conditions but are comparable for typical operating points.

Q: Are there compliance or regulatory differences?

A: No. Both devices are ROHS3 compliant, MSL 1 rated, REACH unaffected, and classified as EAR99. Regulatory documentation and supply chain requirements are equivalent.

Q: Why is the SMP3003-TL-1E obsolete?

A: The SMP3003-TL-1E is classified as obsolete by onsemi. The IXTA120P065T, manufactured by IXYS, is an active product with confirmed long-term availability, making it the preferred choice for new designs and production continuity.

Q: How do gate charge differences affect circuit design?

A: The IXTA120P065T's lower gate charge (185 nC versus 280 nC) results in faster switching transitions and reduced gate driver power requirements. Existing gate driver circuits designed for the SMP3003-TL-1E will function with the IXTA120P065T, though optimization may improve efficiency.

Q: What is the temperature operating range difference?

A: The IXTA120P065T specifies a wider operating temperature range (-55°C to 150°C) compared to the SMP3003-TL-1E (150°C maximum). This provides additional design margin for low-temperature applications.
