IRLR7833CPBF N-Channel 30V 140A MOSFET Equivalent & Substitute Parts

Part Overview

The IRLR7833CPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 30V drain-to-source voltage with 140A continuous drain current at 25°C ambient temperature. The device is housed in a TO-252AA (DPAK) surface mount package and dissipates up to 140W under thermal conditions. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing production support, design updates, and inventory management. Substitute parts must maintain electrical compatibility across voltage ratings, current handling capacity, and package form factor while accommodating variations in thermal performance and gate charge characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRLR7833CPBF is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain-to-Source Voltage (Vdss): Must equal 30V
• FET Type: Must be N-Channel
• Technology: Must be MOSFET (Metal Oxide)
• Package / Case: Must be TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Must be Surface Mount
• Gate Voltage (Vgs Max): Must support ±20V or greater

Secondary Compatibility Parameters:

• Continuous Drain Current (Id) @ 25°C: Substitute must meet or exceed 140A (Ta) rating
• Power Dissipation (Max): Substitute must support minimum 140W (Tc)
• Drive Voltage: Substitute must operate at 4.5V and 10V gate drive levels

The substitute parts listed below satisfy all primary criteria and maintain electrical compatibility within the specified parameter ranges. Variations in gate charge, input capacitance, and on-resistance characteristics are acceptable provided the primary electrical and mechanical requirements are met.

Engineering Selection Recommendations

Primary Recommendation: NVD4C05NT4G (onsemi)

The NVD4C05NT4G is classified as Active product status, ensuring long-term availability and manufacturing support. This device carries AEC-Q101 automotive qualification and ROHS3 compliance. While the continuous drain current rating of 90A (Tc) is below the 140A specification of the IRLR7833CPBF, the thermal power dissipation of 57W (Tc) and gate charge characteristics of 14 nC @ 4.5V provide suitable performance for applications where the full 140A rating is not required. The device operates across the full temperature range of -55°C to 175°C (TJ).

Secondary Recommendation: TSM040N03CP ROG (Taiwan Semiconductor Corporation)

The TSM040N03CP ROG is classified as Active product status with ROHS3 compliance. This device delivers 90A continuous drain current (Tc) and 88W power dissipation (Tc), providing closer thermal performance alignment to the original specification. The gate charge of 53 nC @ 4.5V and on-resistance of 4 mOhm @ 24A, 10V support efficient switching operation. Moisture sensitivity level is MSL 3 (168 Hours), requiring controlled storage conditions compared to the MSL 1 rating of the main part.

Tertiary Options: STD100N3LF3 and STD150N3LLH6 (STMicroelectronics)

Both STMicroelectronics devices are classified as Obsolete. The STD100N3LF3 and STD150N3LLH6 deliver 80A continuous drain current (Tc) and 110W power dissipation (Tc). The STD150N3LLH6 features superior on-resistance of 2.8 mOhm @ 40A, 10V. These devices are suitable for applications where current requirements are below 140A and where obsolete component sourcing is acceptable.

Not Recommended: AOD514 (Alpha & Omega Semiconductor Inc.)

The AOD514 is classified as Not For New Designs. The continuous drain current of 46A (Tc) and power dissipation of 50W (Tc) fall significantly below the 140A and 140W specifications of the IRLR7833CPBF, making this device unsuitable for direct substitution in applications requiring full rated performance.

Frequently Asked Questions (FAQ)

Q: Can the NVD4C05NT4G replace the IRLR7833CPBF in all applications?

A: The NVD4C05NT4G maintains electrical compatibility across voltage rating (30V Vdss), package form factor (TO-252-3 DPAK), and gate drive levels (4.5V, 10V). However, the continuous drain current rating of 90A (Tc) is lower than the 140A specification of the IRLR7833CPBF. Substitution is valid for applications where the actual operating current does not exceed 90A continuous drain current at 25°C ambient temperature.

Q: What is the significance of the Ta versus Tc current ratings?

A: Ta denotes continuous drain current at 25°C ambient temperature, while Tc denotes continuous drain current at 25°C case temperature. The IRLR7833CPBF specifies 140A (Ta). Substitute parts may specify current ratings at case temperature (Tc), which reflects thermal management through the package. Direct current comparison requires consideration of thermal conditions in the application.

Q: Why does TSM040N03CP ROG have MSL 3 instead of MSL 1?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions of 30°C and 85% relative humidity before baking is required. MSL 1 (Unlimited) allows indefinite storage without baking. MSL 3 (168 Hours) requires baking after 168 hours of exposure. Applications with extended storage or high-humidity environments should prioritize NVD4C05NT4G or other MSL 1 rated alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. The main part IRLR7833CPBF does not specify RoHS status in the provided data. ROHS3 compliance ensures restriction of hazardous substances in accordance with EU Directive 2011/65/EU.

Q: Can AOD514 be used as a substitute?

A: The AOD514 meets the primary substitution criteria of 30V Vdss, N-Channel type, MOSFET technology, and TO-252-3 DPAK package. However, the continuous drain current of 46A (Tc) and power dissipation of 50W (Tc) are substantially below the 140A and 140W ratings of the IRLR7833CPBF. The AOD514 is classified as Not For New Designs. Substitution is limited to applications where operating current does not exceed 46A and where component obsolescence is acceptable.

Q: What are the on-resistance differences among substitute parts?

A: On-resistance (Rds On) values vary across substitute parts: STD150N3LLH6 features 2.8 mOhm @ 40A, 10V; STD100N3LF3 features 5.5 mOhm @ 40A, 10V; NVD4C05NT4G features 4.1 mOhm @ 45A, 10V; TSM040N03CP ROG features 4 mOhm @ 24A, 10V; AOD514 features 6.5 mOhm @ 20A, 10V. Lower on-resistance reduces conduction losses and heat generation. Selection depends on application power dissipation requirements and thermal management capability.

Q: Is automotive qualification required for substitution?

A: Automotive qualification (AEC-Q101) is specified only for NVD4C05NT4G. Applications requiring automotive-grade components should prioritize this device. Other substitute parts do not carry automotive qualification in the provided data.

Q: What is the operating temperature range for each substitute?

A: NVD4C05NT4G and STD100N3LF3 operate across -55°C to 175°C (TJ). STD150N3LLH6 specifies 175°C (TJ) maximum without lower temperature specification. TSM040N03CP ROG specifies 150°C (TJ) maximum. AOD514 specifies -55°C to 175°C (TJ). Applications requiring full temperature range operation should verify compatibility with the specific substitute part's temperature specification.
