IRF2804STRRPBF N-Channel 40V 75A MOSFET Equivalent & Substitute Parts

Part Overview

The IRF2804STRRPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 40V drain-to-source voltage and 75A continuous drain current in a D2PAK surface mount package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 175°C and dissipates up to 300W at the case temperature. Substitutes must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the D2PAK package form factor.

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

IRF2804STRLPBF is the direct parametric equivalent to IRF2804STRRPBF. Both devices share identical electrical specifications: 40V Vdss, 75A continuous drain current, 2mOhm Rds On, and 300W power dissipation. The primary distinction is product status: IRF2804STRLPBF is active and available in Cut Tape and Digi-Reel packaging, whereas IRF2804STRRPBF is obsolete. This substitute provides seamless compatibility for existing designs without performance trade-offs.

Enhanced Performance Alternatives:

PSMN1R1-40BS,118 and STB270N4F3 offer superior current handling and reduced on-state resistance while maintaining 40V Vdss and D2PAK packaging. PSMN1R1-40BS,118 delivers 120A continuous current with 1.3mOhm Rds On, reducing conduction losses. STB270N4F3 provides the highest current rating at 160A with 2.5mOhm Rds On and includes AEC-Q101 automotive qualification. Both are active products with full RoHS3 compliance.

PSMN2R2-40BS,118 offers a balanced alternative with 100A continuous current and 2.2mOhm Rds On, suitable for applications requiring moderate current enhancement over the original 75A specification.

Considerations for Obsolete Alternatives:

BUK661R9-40C,118 is classified as obsolete despite meeting electrical requirements (40V, 120A, 1.9mOhm Rds On). While parametrically compatible, procurement of this device may face supply constraints. Nexperia's active PSMN series provides superior availability.

Renesas Alternative:

NP109N04PUG-E1-AY maintains 40V Vdss and exceeds current requirements at 110A. However, power dissipation is specified at 220W (Tc), which is lower than the original 300W rating. This device is suitable only for applications where thermal headroom is not critical.

Compliance Status:

All recommended substitutes maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can IRF2804STRLPBF directly replace IRF2804STRRPBF without circuit modification?

A: Yes. IRF2804STRLPBF is a parametric equivalent with identical electrical specifications. The only difference is product status (active vs. obsolete) and packaging format (Cut Tape/Digi-Reel vs. standard reel). No circuit changes are required.

Q: What is the primary advantage of PSMN1R1-40BS,118 over the original IRF2804STRRPBF?

A: PSMN1R1-40BS,118 provides 120A continuous current capacity (versus 75A) and lower on-state resistance of 1.3mOhm (versus 2.0mOhm). This reduces conduction losses and heat generation in high-current applications. Both maintain 40V Vdss and D2PAK packaging.

Q: Is STB270N4F3 suitable for automotive applications?

A: Yes. STB270N4F3 carries AEC-Q101 automotive qualification and is manufactured by STMicroelectronics. It provides 160A continuous current, 2.5mOhm Rds On, and 330W power dissipation in D2PAK packaging, all within the 40V Vdss class.

Q: Why is NP109N04PUG-E1-AY listed as a substitute if its power dissipation is lower?

A: NP109N04PUG-E1-AY meets the core electrical requirements (40V Vdss, 110A continuous current, TO-263-3 package) and is an active product. However, its 220W power dissipation rating is lower than the original 300W specification. Selection depends on thermal design margins in the target application.

Q: Are all substitute parts available in the same D2PAK package?

A: All substitutes use D2PAK (TO-263-3) surface mount packaging with 2 leads plus tab configuration, ensuring mechanical compatibility with existing PCB layouts and thermal management designs.

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

A: Both are tape-and-reel formats for automated assembly. Cut Tape involves individual component strips cut to length, while Digi-Reel provides continuous reel packaging. Electrical and thermal performance are identical; packaging choice depends on production volume and assembly equipment compatibility.

Q: Can PSMN2R2-40BS,118 be used in place of PSMN1R1-40BS,118?

A: Both are Nexperia active products with 40V Vdss and D2PAK packaging. PSMN2R2-40BS,118 provides 100A continuous current versus PSMN1R1-40BS,118's 120A. Selection depends on circuit current requirements; PSMN1R1-40BS,118 offers higher current capacity and lower Rds On for superior performance.

Q: What compliance certifications apply to all recommended substitutes?

A: All substitutes maintain RoHS3 compliance, Moisture Sensitivity Level 1 (unlimited shelf life), and REACH unaffected status. STB270N4F3 additionally carries AEC-Q101 automotive qualification.
