IRF7811AVPBF N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF7811AVPBF is an N-Channel MOSFET manufactured by Infineon Technologies, rated for 30V drain-to-source voltage with 10.8A continuous drain current at 25°C. This device is part of the HEXFET® series and features a surface mount 8-SO package. The IRF7811AVPBF is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Suitable alternatives must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while conforming to the same package footprint and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IRF7811AVPBF are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain-to-Source Voltage (Vdss): Must equal 30V
• Continuous Drain Current (Id): Must be within 10.3A to 10.8A range at 25°C
• Package Type: Must be 8-SOIC (0.154", 3.90mm Width) surface mount
• Gate Threshold Voltage: Must be ≤3V @ 250µA
• Operating Temperature Range: Must support -55°C to 150°C
• RoHS3 Compliance: Required for regulatory compatibility

Secondary Compatibility Parameters:

• On-Resistance (Rds On): Acceptable range 12-14 mOhm at specified conditions
• Gate Charge (Qg): Acceptable range 24-26 nC
• Power Dissipation: Acceptable range 1.5W to 3.1W
• Vgs (Max): Must support ±20V

The two qualified substitutes (AO4468 and DMN3016LSS-13) meet all critical parameters and maintain functional equivalence within the specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

AO4468 (Alpha & Omega Semiconductor Inc.)

The AO4468 is a direct electrical equivalent with matching 30V Vdss and 10.5A continuous drain current. This substitute maintains the same package footprint and thermal operating range. The AO4468 carries ROHS3 compliance and REACH unaffected status, meeting regulatory requirements. Current product status is "Not For New Designs," indicating the part is in mature production phase with stable supply. The AO4468 is suitable for applications where the slightly higher power dissipation rating (3.1W vs. 2.5W) is acceptable and where design flexibility permits use of a part not recommended for new development.

DMN3016LSS-13 (Diodes Incorporated)

The DMN3016LSS-13 is an active product with 10.3A continuous drain current and 30V Vdss rating, providing the closest electrical match to the IRF7811AVPBF. This substitute features superior on-resistance characteristics (12 mOhm vs. 14 mOhm) and lower power dissipation (1.5W vs. 2.5W), offering thermal performance advantages in power-limited applications. The DMN3016LSS-13 maintains identical package geometry, operating temperature range, and compliance certifications. Active product status ensures long-term availability and supply chain stability. This substitute is the preferred choice for new designs and applications requiring sustained component availability.

Frequently Asked Questions (FAQ)

Q: Can the AO4468 and DMN3016LSS-13 be used interchangeably with the IRF7811AVPBF?

A: Both substitutes are electrically compatible within the specified parameter envelope. All three devices share identical 30V Vdss rating, 8-SOIC package footprint, and operating temperature range (-55°C to 150°C). Continuous drain current ratings are within 10.3A to 10.8A, and on-resistance values fall within acceptable limits. Direct PCB substitution is feasible without circuit redesign.

Q: What is the difference in on-resistance between these parts?

A: The IRF7811AVPBF specifies 14 mOhm @ 15A, 4.5V. The AO4468 specifies 14 mOhm @ 11.6A, 10V. The DMN3016LSS-13 specifies 12 mOhm @ 12A, 10V. The DMN3016LSS-13 exhibits lower on-resistance, resulting in reduced power dissipation and heat generation in switching applications.

Q: Are there package compatibility concerns?

A: All three parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints are identical, and no layout modifications are required for substitution.

Q: Which substitute should be selected for new product designs?

A: The DMN3016LSS-13 is recommended for new designs due to its active product status, superior thermal characteristics, and long-term supply availability. The AO4468 is suitable for legacy system maintenance where the part is already qualified.

Q: Do these substitutes meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance requirements are equivalent across all three devices.

Q: What is the significance of product status (Discontinued vs. Active)?

A: The IRF7811AVPBF is discontinued at DiGi Electronics, indicating no new stock availability. The AO4468 is "Not For New Designs," meaning it is available but not recommended for new development. The DMN3016LSS-13 is "Active," ensuring ongoing production and supply chain support for both new and existing applications.
