IRLS3036TRRPBF N-Channel 60V 195A MOSFET Equivalent & Substitute Parts

Part Overview

The IRLS3036TRRPBF is an N-Channel MOSFET manufactured by Infineon Technologies, part of the HEXFET® series. This device is rated for 60V drain-to-source voltage with 195A continuous drain current and 380W power dissipation. The component is packaged in D2PAK (TO-263-3) surface mount configuration with MSL 1 moisture sensitivity rating.

The IRLS3036TRRPBF is currently listed as Obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute selection must maintain compatibility across electrical parameters, thermal performance, and mechanical packaging.

Substitute Part Grouping Explanation

Substitute parts for the IRLS3036TRRPBF are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent (Direct Replacement): Parts that maintain identical or equivalent electrical specifications, allowing direct substitution without circuit redesign. The primary criterion is matching drain current rating (195A) and on-state resistance characteristics at specified gate voltage conditions.

Functional Equivalent (Reduced Current Rating): Parts that operate at the same voltage rating (60V) but with reduced continuous drain current (120A instead of 195A). These substitutes are suitable for applications where the full 195A current capability is not required. Functional equivalents must maintain compatible gate threshold voltage, power dissipation capability, and thermal characteristics within acceptable operating margins.

Key Parameters Determining Substitution:

Drain-to-Source Voltage (Vdss): Must equal 60V
Package Type: Must be D2PAK (TO-263-3) or compatible surface mount package
Operating Temperature Range: Must support -55°C to 175°C
Gate Threshold Voltage: Must be compatible with existing gate drive circuitry
On-State Resistance: Must not exceed application requirements
Moisture Sensitivity Level: Must be MSL 1 or equivalent

Engineering Selection Recommendations

Parametric Equivalent - Recommended First Choice:

IRLS3036TRLPBF is the primary equivalent for IRLS3036TRRPBF. Both devices share identical electrical specifications (195A continuous drain current, 2.4mOhm on-state resistance, 140nC gate charge) and are packaged in D2PAK. The IRLS3036TRLPBF is currently in Active product status with 1233 pieces in stock, providing immediate availability and design continuity. Both parts are ROHS3 compliant and carry REACH Unaffected status. The only difference is packaging format: IRLS3036TRLPBF is supplied in Cut Tape and Digi-Reel format versus the original Tape & Reel configuration.

Functional Equivalents - Reduced Current Applications:

For applications where continuous drain current requirements do not exceed 120A, the following active parts provide suitable alternatives:

BUK762R6-60E,118 (Nexperia TrenchMOS™) offers 120A continuous current with 2.6mOhm on-state resistance and 140nC gate charge matching the original part's gate charge specification. This part is AEC-Q101 automotive qualified and carries 5583 pieces in stock.

PSMN1R7-60BS,118 (Nexperia) provides the lowest on-state resistance at 2.0mOhm with 120A continuous current and 137nC gate charge. This part is active status with 1900 pieces available.

SUM50020EL-GE3 (Vishay Siliconix TrenchFET®) matches the original gate threshold voltage of 2.5V and offers 120A continuous current with 2.1mOhm on-state resistance. This part is active status with 1133 pieces in stock.

Intermediate Current Option:

STH260N6F6-2 (STMicroelectronics DeepGATE™/STripFET™ VI) provides 180A continuous drain current, bridging the gap between full 195A and reduced 120A options. This part is packaged in H2PAK-2 (compatible with D2PAK footprint) and is active status with 33400 pieces in stock. Gate threshold voltage is 4.0V, requiring verification of gate drive compatibility.

Parts to Avoid:

BUK962R8-60E,118 is listed as Obsolete and should not be selected for new designs despite availability of 997 pieces.

FDB024N06 is in Last Time Buy status and should not be selected for ongoing production.

IPB120N06S402ATMA2 is automotive-grade (AEC-Q101) but carries significantly reduced power dissipation (188W versus 380W) and should only be selected if thermal requirements permit.

Frequently Asked Questions (FAQ)

Q: Can IRLS3036TRLPBF directly replace IRLS3036TRRPBF without circuit modification?

A: Yes. IRLS3036TRLPBF is a parametric equivalent with identical electrical specifications. The only difference is packaging format (Cut Tape/Digi-Reel versus Tape & Reel). No circuit redesign is required. Both parts are ROHS3 compliant and REACH Unaffected.

Q: What is the primary limitation when selecting 120A-rated substitutes for the 195A IRLS3036TRRPBF?

A: The 120A-rated substitutes (BUK762R6-60E,118, PSMN1R7-60BS,118, SUM50020EL-GE3, FDB024N06) are suitable only for applications where the maximum continuous drain current does not exceed 120A. Applications requiring the full 195A capability must use IRLS3036TRLPBF or STH260N6F6-2 (180A).

Q: Are there package compatibility concerns with STH260N6F6-2?

A: STH260N6F6-2 uses H2PAK-2 packaging instead of D2PAK. While both are surface mount packages in the TO-263 family with compatible pin configurations, PCB layout verification is required to confirm footprint compatibility. The H2PAK-2 package may have different thermal pad dimensions.

Q: Which substitute offers the best on-state resistance performance?

A: PSMN1R7-60BS,118 provides the lowest on-state resistance at 2.0mOhm @ 25A, 10V. However, this specification is measured at lower current than the original part's 2.4mOhm @ 165A, 10V. Direct comparison requires evaluation at identical test conditions.

Q: What gate drive voltage compatibility issues should be considered?

A: The original IRLS3036TRRPBF has Vgs(th) of 2.5V @ 250µA. Substitutes with higher threshold voltages (4.0V or 4.5V) may require gate drive circuit verification to ensure adequate gate voltage margin. BUK962R5-60E,118 and SUM50020EL-GE3 maintain the 2.5V threshold, simplifying gate drive compatibility.

Q: Is automotive qualification required for substitute selection?

A: Automotive qualification (AEC-Q101) is not inherent to the original IRLS3036TRRPBF. However, several substitutes carry AEC-Q101 certification (BUK762R4-60E,118, BUK762R6-60E,118, BUK962R5-60E,118, BUK962R8-60E,118, IPB120N06S402ATMA2). Selection of automotive-qualified parts is application-dependent and should be specified by design requirements.

Q: What is the significance of product status (Active, Obsolete, Last Time Buy)?

A: Product status indicates supply availability and manufacturer support. Active parts (IRLS3036TRLPBF, BUK762R6-60E,118, PSMN1R7-60BS,118, STH260N6F6-2, SUM50020EL-GE3) are recommended for new designs and ongoing production. Last Time Buy (FDB024N06) and Obsolete (IRLS3036TRRPBF, BUK962R8-60E,118) parts should be avoided for new designs.

Q: How does gate charge (Qg) affect substitute selection?

A: Gate charge determines gate drive power requirements and switching speed. The original part specifies 140nC @ 4.5V. Substitutes with significantly higher gate charge (FDB024N06 at 226nC) may require gate drive circuit adjustment. Lower gate charge (BUK962R8-60E,118 at 92nC) reduces gate drive power but may affect switching characteristics.

Q: Are all substitutes ROHS3 compliant?

A: All listed substitutes are ROHS3 compliant. All parts carry REACH Unaffected status. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, matching the original specification.
