FDMA7630 Equivalent & Substitute Parts

Part Overview

The FDMA7630 is an N-Channel MOSFET manufactured by onsemi, rated for 30V drain-to-source voltage with 11A continuous drain current at 25°C. This device is housed in a 6-MicroFET (2x2) surface mount package and is designed for power switching applications requiring compact form factors and efficient thermal performance. The part is Active in product status and RoHS3 compliant. Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatibility with the application requirements.

Substitute Part Grouping Explanation

Substitute parts for the FDMA7630 are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss) rating must be equal to or greater than 30V
Continuous Drain Current (Id) must support the application requirement of 11A or be within acceptable operating margins
Gate threshold voltage (Vgs(th)) must fall within compatible drive voltage ranges (4.5V to 10V)
On-resistance (Rds On) must not exceed values that would cause unacceptable power dissipation in the target application
Operating temperature range must encompass -55°C to 150°C
Surface mount package configuration with exposed pad design
RoHS3 compliance and MSL 1 rating required

Substitution Logic: Parts are grouped as direct substitutes when they meet or exceed the FDMA7630 electrical specifications while maintaining thermal and package compatibility. Parts with higher voltage ratings (40V) are acceptable substitutes provided current handling and thermal characteristics remain within acceptable limits for the application. Parts with slightly lower current ratings (8A to 10A) may serve as substitutes in applications where the full 11A capability is not required.

Engineering Selection Recommendations

DMN3016LFDE-7 (Diodes Incorporated): This part is an equivalent substitute for applications where the full 11A capability of the FDMA7630 is not required. The DMN3016LFDE-7 provides 10A continuous drain current with a 30V Vdss rating, matching the voltage specification of the main part. The on-resistance of 12 mOhm at 11A, 10V is superior to the FDMA7630 specification. All compliance certifications (RoHS3, MSL 1) are identical. Package differences (6-PowerUDFN versus 6-WDFN) require PCB layout verification for pin compatibility and thermal performance.

DMN4020LFDE-7 (Diodes Incorporated): This part serves as a substitute for applications operating at lower current levels (8A maximum). The 40V Vdss rating provides additional voltage margin beyond the 30V requirement. On-resistance is 20 mOhm at 8A, 10V, which is higher than the FDMA7630 but acceptable for reduced current operation. Power dissipation is lower due to the reduced current rating. RoHS3 and MSL 1 compliance are maintained. Package compatibility requires verification.

PMPB11EN,115 (Nexperia USA Inc.): This part is a direct substitute for the FDMA7630 in applications requiring 9A continuous drain current. The 30V Vdss rating matches the main part exactly. On-resistance of 14.5 mOhm at 9A, 10V is comparable to the FDMA7630 specification. Power dissipation rating of 1.7W (Ta) or 12.5W (Tc) provides flexibility depending on thermal management approach. All compliance certifications are equivalent. Package type (6-UDFN Exposed Pad) is similar to the main part but requires pin-out verification.

All substitute parts maintain Active product status and are suitable for long-term design implementation.

Frequently Asked Questions (FAQ)

Q: Can the DMN3016LFDE-7 replace the FDMA7630 in all applications?

A: The DMN3016LFDE-7 is suitable for applications where continuous drain current does not exceed 10A. If the application requires the full 11A capability of the FDMA7630, the DMN3016LFDE-7 is not appropriate. Verify application current requirements before substitution.

Q: What is the primary difference between the DMN4020LFDE-7 and the FDMA7630?

A: The DMN4020LFDE-7 has a higher Vdss rating (40V versus 30V) and lower maximum continuous drain current (8A versus 11A). It is suitable for applications with lower current requirements and higher voltage margins. The higher on-resistance (20 mOhm) results in greater power dissipation at equivalent current levels.

Q: Are the package types of these substitute parts pin-compatible with the FDMA7630?

A: All substitute parts use 6-pin surface mount packages with exposed pad designs. However, pin assignments and thermal pad dimensions may differ. PCB layout and schematic verification is required before implementation. Consult manufacturer datasheets for detailed package drawings.

Q: Do all substitute parts meet the same compliance requirements as the FDMA7630?

A: Yes. All substitute parts listed are RoHS3 compliant, have MSL 1 (Unlimited) moisture sensitivity ratings, and maintain Active product status. REACH and ECCN classifications are equivalent across all parts.

Q: Which substitute part has the lowest on-resistance?

A: The DMN3016LFDE-7 has the lowest on-resistance at 12 mOhm (measured at 11A, 10V), compared to 13 mOhm for the FDMA7630. This results in lower power dissipation and improved efficiency in switching applications.

Q: Can the PMPB11EN,115 be used as a direct replacement for the FDMA7630?

A: The PMPB11EN,115 is suitable for applications requiring up to 9A continuous drain current. The 30V Vdss rating matches the FDMA7630 specification. Package and pin-out verification is required. If the application requires the full 11A capability, this part is not appropriate.

Q: What thermal considerations apply when substituting these parts?

A: The FDMA7630 has a power dissipation rating of 2.4W (Ta). The DMN3016LFDE-7 and DMN4020LFDE-7 have lower ratings (0.73W and 0.66W respectively) due to reduced current capability. The PMPB11EN,115 offers dual thermal ratings (1.7W Ta / 12.5W Tc), providing flexibility with proper thermal management. Verify thermal performance in the target application environment.

Q: Are there inventory considerations for these substitute parts?

A: All parts listed are in active production with substantial inventory availability. FDMA7630: 17,660 pcs; DMN3016LFDE-7: 15,537 pcs; DMN4020LFDE-7: 6,001 pcs; PMPB11EN,115: 85,663 pcs. Inventory levels may change; verify current availability with suppliers.
