IRFS7534PBF N-Channel 60V 195A MOSFET Equivalent & Substitute Parts

Part Overview

The IRFS7534PBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 60V drain-to-source voltage and 195A continuous drain current in a D2PAK surface mount package. This device is part of the HEXFET® and StrongIRFET™ series and is currently discontinued at DiGi Electronics. Due to its discontinued status, equivalent and substitute parts are necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility with the D2PAK package and preserve critical electrical parameters including voltage rating, current handling capability, and thermal performance.

Substitute Part Grouping Explanation

Substitute parts for the IRFS7534PBF are selected based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

Drain to Source Voltage (Vdss): 60V or higher
Continuous Drain Current (Id): 195A or higher at 25°C
Package Type: D2PAK (TO-263-3) surface mount
FET Type: N-Channel MOSFET
Operating Temperature Range: -55°C to 175°C or equivalent
RoHS3 Compliance

Secondary Compatibility Factors:

Rds On (Max): Lower or equal values preferred for thermal efficiency
Gate Charge (Qg): Lower values reduce switching losses
Power Dissipation: Equal or higher ratings ensure thermal headroom
Vgs(th) and Vgs (Max): Must be compatible with drive circuitry

Substitutes are grouped into two categories: direct equivalents (same voltage and current ratings) and functional alternatives (higher voltage ratings or different current specifications that maintain system-level compatibility).

Engineering Selection Recommendations

Recommended Primary Substitute: IRLS3036TRLPBF

The IRLS3036TRLPBF is the optimal direct substitute for the IRFS7534PBF. Both devices share identical voltage (60V) and current (195A) ratings, D2PAK packaging, and operating temperature range (-55°C to 175°C). The IRLS3036TRLPBF is currently in active production status with 1233 pieces in stock, ensuring supply continuity. This part demonstrates improved thermal performance with 380W maximum power dissipation compared to 294W in the original part, and lower gate charge (140 nC @ 4.5V) reduces switching losses. Both parts are ROHS3 compliant and carry identical REACH and ECCN classifications.

Alternative Substitute: IRFS3107TRLPBF

The IRFS3107TRLPBF provides a functional alternative with a higher voltage rating (75V) while maintaining the same 195A current rating and D2PAK package. This part is suitable for applications where voltage margin is beneficial. It is currently in active production with 6677 pieces in stock. The higher voltage rating (75V vs. 60V) provides additional design headroom for transient voltage spikes. Power dissipation is 370W, and gate charge is 240 nC @ 10V. This substitute is appropriate when system voltage specifications allow for higher-rated components.

Lower-Priority Alternatives: BUK962R8-60E,118 and NP109N055PUK-E1-AY

BUK962R8-60E,118 (Nexperia) and NP109N055PUK-E1-AY (Renesas) are not recommended as primary substitutes due to reduced current ratings (120A and 110A respectively, compared to 195A). BUK962R8-60E,118 is also marked as obsolete. These parts are suitable only for applications where the full 195A current capability is not required. NP109N055PUK-E1-AY has a lower voltage rating (55V) and reduced current capacity, limiting its applicability.

Compliance and Certification:

All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, ensuring regulatory compatibility with the original IRFS7534PBF.

Frequently Asked Questions (FAQ)

Q: Can IRLS3036TRLPBF directly replace IRFS7534PBF without circuit modifications?

A: Yes. Both parts share identical Vdss (60V), Id (195A), operating temperature range (-55°C to 175°C), and D2PAK packaging. The IRLS3036TRLPBF has lower Rds On and gate charge, which improve performance. No circuit modifications are required.

Q: What is the difference between IRLS3036TRLPBF and IRFS3107TRLPBF?

A: The primary difference is voltage rating: IRLS3036TRLPBF is rated for 60V (matching the original part), while IRFS3107TRLPBF is rated for 75V. Both maintain 195A current rating. The IRFS3107TRLPBF is suitable when higher voltage margin is desired. Current handling and package are identical.

Q: Why are BUK962R8-60E,118 and NP109N055PUK-E1-AY not recommended?

A: Both parts have reduced continuous drain current ratings (120A and 110A respectively) compared to the required 195A. BUK962R8-60E,118 is also marked as obsolete. These parts are only suitable for applications with lower current requirements.

Q: Are all substitute parts available in the same packaging?

A: Yes. All recommended substitutes use D2PAK (TO-263-3) surface mount packaging, ensuring mechanical and thermal compatibility with the original IRFS7534PBF footprint.

Q: What is the significance of gate charge differences between substitutes?

A: Lower gate charge reduces switching losses and improves efficiency. IRLS3036TRLPBF has 140 nC @ 4.5V (lowest), while IRFS7534PBF has 279 nC @ 10V. Lower gate charge allows faster switching and reduces driver power consumption.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All recommended substitute parts are ROHS3 compliant and carry identical REACH unaffected status, ensuring regulatory compatibility.

Q: Which substitute has the best thermal performance?

A: IRLS3036TRLPBF offers the highest maximum power dissipation at 380W (Tc), compared to 294W for the original IRFS7534PBF, providing superior thermal headroom in high-power applications.

Q: Can IRFS3107TRLPBF be used in a 60V system?

A: Yes. IRFS3107TRLPBF is rated for 75V, which exceeds the 60V system requirement. Higher voltage-rated devices operate safely in lower-voltage applications and provide additional transient protection.
