IRLR7807ZTRLPBF N-Channel 30V 43A MOSFET Equivalent & Substitute Parts

Part Overview

The IRLR7807ZTRLPBF is an N-Channel MOSFET manufactured by Infineon Technologies, part of the HEXFET® series. This device is rated for 30V drain-to-source voltage with 43A continuous drain current and 40W power dissipation in a Surface Mount TO-252AA (DPAK) package. The component is classified as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and system maintenance. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating the same or compatible package footprints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRLR7807ZTRLPBF is determined by strict alignment of the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 30V
• Package Type: Must be TO-252-3 DPAK (Surface Mount, 2 Leads + Tab)
• FET Type: N-Channel MOSFET (Metal Oxide Semiconductor)
• Mounting: Surface Mount

Secondary Compatibility Criteria:

• Continuous Drain Current (Id): Substitute must support minimum 43A or provide equivalent thermal performance
• Rds On (On-State Resistance): Lower or equivalent values ensure thermal compatibility
• Gate Charge (Qg): Similar values maintain switching characteristics
• Operating Temperature Range: Must support -55°C to 175°C minimum
• Moisture Sensitivity: MSL 1 (Unlimited) preferred for supply chain flexibility

Three substitute parts meet these criteria with varying performance enhancements and product status classifications.

Parameter Comparison

Engineering Selection Recommendations

BUK9214-30A,118 (Nexperia USA Inc.)

This substitute provides enhanced current handling (63A vs. 43A) and superior power dissipation (107W vs. 40W), making it suitable for applications requiring thermal headroom. The device maintains 30V Vdss rating and DPAK package compatibility. Although classified as Obsolete, it carries AEC-Q101 Automotive qualification and ROHS3 compliance, providing regulatory assurance. The higher gate charge (31 nC) may require driver circuit evaluation in high-frequency switching applications. Recommended for designs where increased current capacity and thermal performance justify the substitution.

DMN3016LK3-13 (Diodes Incorporated)

This substitute is classified as Active product status, ensuring long-term supply availability and manufacturing support. It maintains 30V Vdss and TO-252-3 package compatibility with equivalent Rds On performance (12 mOhm). However, the continuous drain current rating (12.4A Ta) is significantly lower than the main part (43A Tc), restricting this substitute to applications with reduced current requirements. ROHS3 compliance and MSL 1 rating support modern supply chain requirements. The lower operating temperature maximum (150°C vs. 175°C) may limit use in high-temperature environments. Recommended for low-to-medium current applications where supply continuity is prioritized.

NTD4813NHT4G (onsemi)

This substitute offers dual current ratings (7.6A Ta / 40A Tc) with Active product status, ensuring sustained availability. The 40A Tc rating closely matches the main part's 43A Tc specification, providing thermal equivalence. Gate charge (10 nC) is nearly identical to the main part (11 nC), supporting direct driver compatibility. ROHS3 compliance and full temperature range support (-55°C to 175°C) align with the main part specifications. The lower Ta rating (7.6A) reflects conservative ambient temperature assumptions; Tc rating governs thermal design. Recommended as the primary substitute for direct replacement in existing designs with minimal circuit modification.

Frequently Asked Questions (FAQ)

Q: Can BUK9214-30A,118 be used as a direct replacement for IRLR7807ZTRLPBF?

A: Yes, with circuit evaluation. Both devices share 30V Vdss, DPAK package, and -55°C to 175°C operating range. The BUK9214 provides higher current (63A vs. 43A) and power dissipation (107W vs. 40W). The increased gate charge (31 nC vs. 11 nC) requires verification that the gate driver can supply the additional charge without exceeding switching time specifications. Thermal design may benefit from the enhanced power dissipation capability.

Q: Why is DMN3016LK3-13 listed as a substitute if its current rating is only 12.4A?

A: DMN3016LK3-13 is included as a substitute for applications where the full 43A current capacity is not required. Its Active product status provides supply continuity advantages over the Obsolete main part. The 30V Vdss rating and DPAK package maintain electrical and mechanical compatibility. Selection depends on actual circuit current requirements; this part is suitable only for designs operating below 12.4A continuous drain current.

Q: What is the difference between Ta and Tc current ratings in NTD4813NHT4G?

A: Ta (ambient temperature) rating of 7.6A assumes operation at elevated ambient temperatures with limited heatsinking. Tc (case temperature) rating of 40A assumes the device case is maintained at 25°C through active cooling or heatsinking. For thermal design purposes, use the Tc rating (40A) when adequate thermal management is provided, matching the main part's 43A Tc specification. The Ta rating is conservative and does not limit substitution in properly cooled applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. BUK9214-30A,118, DMN3016LK3-13, and NTD4813NHT4G are all ROHS3 compliant. The main part (IRLR7807ZTRLPBF) RoHS status is not specified in the provided data. All substitutes meet current environmental and regulatory requirements for new designs and production.

Q: Can I use NTD4813NHT4G in a high-frequency switching application?

A: Yes. The NTD4813NHT4G gate charge (10 nC @ 4.5V) is nearly identical to the main part (11 nC @ 4.5V), ensuring compatible switching characteristics and driver requirements. Verify that the gate driver voltage (4.5V to 11.5V range) matches your circuit design. The Active product status and full temperature range support high-frequency applications without additional constraints.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special storage, handling, or baking procedures before soldering. All listed parts (main and substitutes) carry MSL 1 rating, simplifying supply chain management and reducing production risk. This classification supports flexible inventory practices and extended shelf life.

Q: Which substitute should I select for a new design?

A: For new designs, NTD4813NHT4G (onsemi) is recommended as the primary choice due to Active product status, ensuring long-term availability and manufacturing support. The 40A Tc rating provides thermal equivalence to the main part, and the 10 nC gate charge maintains driver compatibility. ROHS3 compliance and full temperature range (-55°C to 175°C) support modern regulatory requirements. DMN3016LK3-13 is suitable only if current requirements are below 12.4A.
