IRFR3707ZPBF N-Channel MOSFET 30V 56A Equivalent & Substitute Parts

Part Overview

The IRFR3707ZPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 30V drain-to-source voltage and 56A continuous drain current at 25°C. This device is packaged in TO-252-3 (DPAK) surface mount configuration and is part of the HEXFET® series. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional compatibility within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRFR3707ZPBF is determined by strict equivalence across the following critical parameters:

Voltage Rating: All substitute parts must maintain Vdss of 30V to ensure safe operation in the original circuit design.

Package Type: All substitutes must use TO-252-3 (DPAK) surface mount configuration to ensure mechanical and thermal compatibility with existing PCB layouts.

Drain Current Capability: Substitute parts must support the required continuous drain current at 25°C. Parts with lower Id ratings may be acceptable only if the application does not require the full 56A specification.

On-State Resistance (Rds On): Substitute parts must maintain comparable Rds On values to ensure similar power dissipation and thermal performance.

Gate Drive Voltage: Substitute parts must be compatible with standard gate drive voltages (4.5V and 10V) used in the original design.

Temperature Range: Substitute parts must support the operating temperature range of -55°C to 175°C (TJ).

Compliance: All substitute parts must maintain ROHS3 compliance and equivalent regulatory status (REACH Unaffected, EAR99 classification).

Parameter Comparison

Engineering Selection Recommendations

IPD090N03LGATMA1 (Infineon Technologies OptiMOS™ Series)

This part is the manufacturer-recommended substitute. It maintains 30V Vdss rating and TO-252-3 package compatibility. The continuous drain current rating of 40A (Tc) is lower than the original 56A specification. This substitute is suitable for applications where the circuit design does not require the full 56A capability. The part is currently in active production status with 5400 units in stock. ROHS3 compliance and regulatory status are equivalent to the main part.

DMN3010LK3-13 (Diodes Incorporated)

This part maintains 30V Vdss and TO-252-3 package compatibility. The continuous drain current rating of 43A (Tc) is lower than the original 56A specification. The maximum operating temperature is limited to 150°C (TJ), which is 25°C lower than the original part. This part is currently in active production status with 9413 units in stock. ROHS3 compliance and regulatory status are equivalent. Selection of this part requires verification that the application does not exceed 150°C junction temperature.

FDD8876 (onsemi PowerTrench® Series)

This part maintains 30V Vdss and TO-252-3 package compatibility. The continuous drain current rating of 73A (Tc) exceeds the original 56A specification, providing higher current capability. The part is currently in obsolete status. ROHS3 compliance and regulatory status are equivalent. The higher gate charge (47 nC) compared to the original part (14 nC) may require adjustment of gate drive circuit timing parameters.

Frequently Asked Questions (FAQ)

Q: Can IPD090N03LGATMA1 be used as a direct replacement for IRFR3707ZPBF?

A: IPD090N03LGATMA1 is compatible from a voltage rating, package type, and compliance perspective. However, the continuous drain current rating is 40A (Tc) compared to 56A (Tc) for the original part. Direct substitution is valid only if the circuit design does not require continuous drain current exceeding 40A.

Q: What is the primary limitation of DMN3010LK3-13 as a substitute?

A: DMN3010LK3-13 has a maximum operating junction temperature of 150°C (TJ), which is 25°C lower than the original IRFR3707ZPBF specification of 175°C (TJ). Applications operating near the upper temperature limit of the original part may not be compatible with this substitute.

Q: Why does FDD8876 have higher gate charge than the original part?

A: FDD8876 has a gate charge (Qg) of 47 nC compared to 14 nC for IRFR3707ZPBF. This difference reflects different semiconductor process technology and die design. Gate drive circuits must be capable of supplying the higher charge within the required switching time window.

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

A: All substitute parts listed use TO-252-3 (DPAK) surface mount package configuration, ensuring mechanical and thermal compatibility with PCB layouts designed for the original IRFR3707ZPBF.

Q: What is the significance of product status (Active vs. Obsolete) for part selection?

A: Active status indicates current production and long-term availability. Obsolete status indicates the part is no longer manufactured. IPD090N03LGATMA1 and DMN3010LK3-13 are active parts suitable for new designs and long-term production. FDD8876 is obsolete and should be used only when existing inventory is available and long-term supply is not required.

Q: Do all substitute parts meet the same regulatory compliance requirements?

A: All substitute parts listed are ROHS3 compliant, REACH Unaffected, and classified as EAR99. Regulatory compliance is equivalent across all parts.
