IRF3707ZSTRL N-Channel 30V 59A MOSFET Equivalent & Substitute Parts

Part Overview

The IRF3707ZSTRL is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 30V drain-to-source voltage with 59A continuous drain current at 25°C. This device is packaged in D2PAK (TO-263-3) surface mount configuration and is part of the HEXFET® series. The IRF3707ZSTRL is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility across electrical ratings, thermal characteristics, and mechanical packaging to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRF3707ZSTRL is determined by the following critical parameters:

Primary Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 30V
• Package Type: Must be D2PAK (TO-263-3) surface mount configuration
• FET Type: Must be N-Channel
• Technology: Must be MOSFET (Metal Oxide)
• Operating Temperature Range: Must support -55°C to 175°C (TJ)
• Continuous Drain Current (Id): Must meet or exceed application requirements
• On-State Resistance (Rds On): Lower values indicate improved performance
• Gate Threshold Voltage (Vgs(th)): Must be compatible with drive circuitry
• Moisture Sensitivity Level (MSL): Must be MSL 1 (Unlimited)

The substitute parts listed below satisfy these criteria and are qualified as direct replacements based on electrical and mechanical compatibility within the specified parameter ranges.

Engineering Selection Recommendations

PSMN4R3-30BL,118 (Primary Recommendation)

The PSMN4R3-30BL,118 manufactured by Nexperia USA Inc. is the preferred substitute for the IRF3707ZSTRL. This device maintains the 30V Vdss rating and D2PAK package configuration. The PSMN4R3-30BL,118 offers 100A continuous drain current, exceeding the IRF3707ZSTRL specification of 59A, providing design margin for current-handling applications. The on-state resistance of 4.1 mOhm at 15A and 10V is superior to the original part, resulting in lower power dissipation and improved thermal performance. The PSMN4R3-30BL,118 holds Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance and MSL 1 rating confirm environmental and moisture handling compatibility.

PSMN017-30BL,118 (Secondary Recommendation)

The PSMN017-30BL,118 from Nexperia USA Inc. provides an alternative substitute with 32A continuous drain current. This part is suitable for applications where the IRF3707ZSTRL current rating of 59A exceeds design requirements. The PSMN017-30BL,118 maintains 30V Vdss and D2PAK packaging. On-state resistance of 17 mOhm at 10A and 10V is higher than the primary recommendation but acceptable for lower-current applications. ROHS3 compliance and MSL 1 rating are confirmed. Product status is Obsolete.

IPB22N03S4L15ATMA1 (Tertiary Recommendation)

The IPB22N03S4L15ATMA1 from Infineon Technologies is qualified as a substitute with 22A continuous drain current. This part is applicable only to applications where current requirements are significantly lower than the IRF3707ZSTRL specification. The device maintains 30V Vdss and operates across the -55°C to 175°C temperature range. On-state resistance of 14.6 mOhm at 22A and 10V is acceptable for reduced-current designs. ROHS3 compliance and MSL 1 rating are confirmed. Product status is Obsolete. Package designation is PG-TO263-3-2, which is mechanically and electrically equivalent to D2PAK (TO-263-3).

Compliance and Availability Considerations

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures. ROHS3 compliance of the substitute parts addresses environmental regulatory requirements, whereas the original IRF3707ZSTRL is RoHS non-compliant. The PSMN4R3-30BL,118 is the only substitute with Active product status, providing the longest procurement window and supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the IPB22N03S4L15ATMA1 directly replace the IRF3707ZSTRL in all applications?

A: No. The IPB22N03S4L15ATMA1 is rated for 22A continuous drain current, which is significantly lower than the IRF3707ZSTRL specification of 59A. This substitute is suitable only for applications where the actual current requirement does not exceed 22A. Exceeding this rating will result in thermal stress and device failure.

Q: What is the difference between the D2PAK and PG-TO263-3-2 package designations?

A: D2PAK and PG-TO263-3-2 are equivalent package designations for the TO-263-3 surface mount configuration. Both refer to a 3-lead package with 2 leads plus a tab. The mechanical and electrical footprints are identical, allowing direct PCB substitution.

Q: Why is the PSMN4R3-30BL,118 recommended as the primary substitute despite higher gate charge?

A: The PSMN4R3-30BL,118 offers superior on-state resistance (4.1 mOhm versus 9.5 mOhm), resulting in lower power dissipation and improved thermal efficiency. The higher gate charge of 41.5 nC is offset by the Active product status, ensuring long-term availability. Gate charge differences are manageable through drive circuit design and do not preclude substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (IPB22N03S4L15ATMA1, PSMN017-30BL,118, and PSMN4R3-30BL,118) are ROHS3 compliant. The original IRF3707ZSTRL is RoHS non-compliant. Substitution with any of these parts satisfies RoHS regulatory requirements for new designs.

Q: What is the significance of Product Status (Active vs. Obsolete)?

A: Product Status indicates manufacturer support and supply availability. Active status (PSMN4R3-30BL,118) guarantees continued production and long-term procurement capability. Obsolete status (IPB22N03S4L15ATMA1, PSMN017-30BL,118) indicates end-of-life classification; these parts remain available from existing inventory but may face supply constraints over time.

Q: Can the PSMN4R3-30BL,118 be used in applications requiring exactly 59A continuous current?

A: Yes. The PSMN4R3-30BL,118 is rated for 100A continuous drain current, which exceeds the 59A requirement. This provides design margin and thermal headroom, improving reliability and component longevity in current-limited applications.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters are Vdss (30V), FET type (N-Channel), technology (MOSFET Metal Oxide), package (D2PAK TO-263-3), operating temperature range (-55°C to 175°C), and MSL rating (1 Unlimited). Continuous drain current and on-state resistance must meet or exceed application requirements.

Q: Is moisture sensitivity level (MSL) a factor in part selection?

A: Yes. All qualified substitutes maintain MSL 1 (Unlimited), matching the original IRF3707ZSTRL specification. This ensures compatibility with standard PCB assembly processes and storage conditions without special handling requirements.
