IRF7456PBF N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF7456PBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 20V drain-to-source voltage with 16A continuous drain current. This device is part of the HEXFET® series and is designed for surface mount applications in 8-SO packaging. The IRF7456PBF has been discontinued at DiGi Electronics, making identification of functionally equivalent substitute components necessary for ongoing design support, production continuity, and component sourcing.

Substitute parts must maintain compatibility across critical electrical parameters including drain-to-source voltage rating, continuous drain current capacity, on-resistance characteristics, and thermal performance, while accommodating the surface mount 8-SOIC package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRF7456PBF is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• FET Type: Must be N-Channel
• Drain-to-Source Voltage (Vdss): Substitute must equal or exceed 20V
• Continuous Drain Current (Id): Substitute must equal or exceed 16A at 25°C
• On-Resistance (Rds On): Substitute Rds On must not exceed the maximum specified for the IRF7456PBF to maintain equivalent thermal and switching performance
• Power Dissipation: Substitute must support minimum 2.5W thermal rating
• Mounting Type: Must be Surface Mount
• Package: Must be 8-SOIC (0.154", 3.90mm Width) for PCB layout compatibility

Important Compatibility Parameters:

• Gate Threshold Voltage (Vgs(th)): Substitute values must fall within acceptable gate drive voltage ranges
• Gate Charge (Qg): Lower gate charge values improve switching speed; higher values remain acceptable if within driver capability
• Input Capacitance (Ciss): Affects gate drive requirements; substitutes with lower capacitance are preferred
• Operating Temperature Range: Substitute must support -55°C to 150°C (TJ) minimum
• RoHS3 Compliance: Required for regulatory alignment
• MSL Rating: MSL 1 preferred for unlimited shelf life

The DMN3007LSS-13 from Diodes Incorporated meets all critical substitution criteria and is classified as a direct functional equivalent.

Engineering Selection Recommendations

Primary Substitute: DMN3007LSS-13 (Diodes Incorporated)

The DMN3007LSS-13 is the recommended substitute for the discontinued IRF7456PBF based on the following engineering criteria:

Electrical Compatibility:

• Maintains N-Channel MOSFET topology with identical 16A continuous drain current rating
• Vdss rating of 30V exceeds the 20V requirement, providing additional voltage margin for circuit protection
• On-resistance of 7 mOhm @ 15A, 10V is within acceptable tolerance of the original 6.5 mOhm specification
• Gate threshold voltage of 2.1V is functionally equivalent to the 2V specification
• Input capacitance of 2714 pF is lower than the original 3640 pF, resulting in improved gate drive efficiency

Mechanical and Thermal Compatibility:

• Identical 8-SOIC (0.154", 3.90mm Width) package enables direct PCB layout substitution without redesign
• Matching 2.5W power dissipation rating maintains thermal design equivalence
• Operating temperature range of -55°C to 150°C (TJ) matches the original specification

Regulatory and Supply Chain Alignment:

• ROHS3 Compliant status matches original device compliance requirements
• MSL 1 (Unlimited) rating provides equivalent moisture sensitivity handling
• Active product status at Diodes Incorporated ensures ongoing availability and supply chain stability
• REACH Unaffected and EAR99 ECCN classifications maintain regulatory alignment

Implementation Consideration: The higher Vdss rating (30V vs. 20V) of the DMN3007LSS-13 introduces no circuit compatibility issues in applications designed for the 20V IRF7456PBF, as the substitute operates within the original voltage envelope while providing additional design margin.

Frequently Asked Questions (FAQ)

Q: Can the DMN3007LSS-13 be used as a direct replacement for the IRF7456PBF without circuit modifications?

A: Yes. The DMN3007LSS-13 is electrically and mechanically compatible with the IRF7456PBF. Both devices share identical package geometry (8-SOIC), continuous drain current rating (16A), power dissipation (2.5W), and operating temperature range (-55°C to 150°C). The substitute's higher Vdss rating (30V vs. 20V) and lower on-resistance tolerance provide additional circuit margin without requiring design changes.

Q: What is the significance of the higher Vdss rating (30V) on the DMN3007LSS-13 compared to the IRF7456PBF (20V)?

A: The higher Vdss rating indicates the DMN3007LSS-13 can withstand greater drain-to-source voltage stress. In applications designed for 20V operation, this higher rating provides additional safety margin and protection against voltage transients. The substitute remains fully compatible with circuits designed for the 20V device.

Q: Are there differences in gate drive requirements between the IRF7456PBF and DMN3007LSS-13?

A: Gate drive requirements are functionally equivalent. The IRF7456PBF specifies 62 nC gate charge at 5V, while the DMN3007LSS-13 specifies 64.2 nC at 10V. Both devices operate within standard gate driver voltage ranges. The DMN3007LSS-13's lower input capacitance (2714 pF vs. 3640 pF) may result in slightly faster switching transitions, which is beneficial for circuit performance.

Q: Do the packages have identical pinout and footprint?

A: Yes. Both the IRF7456PBF and DMN3007LSS-13 use the 8-SOIC package with 0.154" (3.90mm) width. Pinout and footprint are identical, enabling direct PCB substitution without layout modifications.

Q: What is the product status difference between these devices?

A: The IRF7456PBF has been discontinued at DiGi Electronics, limiting future availability. The DMN3007LSS-13 maintains Active product status at Diodes Incorporated, ensuring ongoing supply chain access and long-term component availability for production and support.

Q: Are both devices RoHS3 compliant?

A: Yes. Both the IRF7456PBF and DMN3007LSS-13 are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting equivalent regulatory and handling requirements.

Q: Can the DMN3007LSS-13 handle the same thermal load as the IRF7456PBF?

A: Yes. Both devices are rated for 2.5W maximum power dissipation and support the same operating temperature range (-55°C to 150°C TJ). Thermal design considerations remain equivalent between the two devices.
