Engineering Selection Recommendations

DMN3007LSSQ-13 (Diodes Incorporated)

The DMN3007LSSQ-13 is an active product with ROHS3 compliance and REACH unaffected status. It provides 16A continuous drain current, exceeding the IRF7455 specification, with on-resistance of 7 mOhm at 15A and 10V, which is lower than the IRF7455. The device supports ±20V gate-source voltage, providing greater gate drive margin than the IRF7455 ±12V rating. All electrical parameters remain within acceptable substitution ranges. The 8-SOIC package with 0.154" width maintains mechanical compatibility.

FDS6670A (Fairchild Semiconductor)

The FDS6670A is an active product in the PowerTrench® series. It provides 13A continuous drain current, which is below the IRF7455 15A specification. On-resistance is 8 mOhm at 13A and 10V. Gate charge is 30 nC at 5V, lower than the IRF7455 56 nC specification. Input capacitance is 2220 pF at 15V, reduced from the IRF7455 3480 pF at 25V. This device is suitable for applications where the 13A current rating is sufficient and lower gate charge is beneficial. The 8-SOIC package maintains mechanical compatibility.

FDS8896 (onsemi)

The FDS8896 is an active product with ROHS3 compliance and REACH unaffected status in the PowerTrench® series. It provides 15A continuous drain current, matching the IRF7455 specification exactly. On-resistance is 6 mOhm at 15A and 10V, which is superior to the IRF7455 7.5 mOhm specification. Gate charge is 67 nC at 10V, slightly higher than the IRF7455 56 nC at 5V. The device supports ±20V gate-source voltage. All electrical parameters are within acceptable substitution ranges. The 8-SOIC package with 0.154" width maintains mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DMN3007LSSQ-13 directly replace the IRF7455 in existing designs?

A: Yes. The DMN3007LSSQ-13 maintains the same 30V Vdss rating, 8-SOIC package configuration, and surface mount footprint as the IRF7455. The 16A continuous drain current exceeds the IRF7455 15A specification, and on-resistance of 7 mOhm at 15A is lower. Gate-source voltage rating of ±20V provides additional margin compared to the IRF7455 ±12V. Pin-to-pin compatibility with the 8-SOIC package allows direct substitution.

Q: What is the primary difference between the FDS6670A and the IRF7455?

A: The FDS6670A has a lower continuous drain current rating of 13A compared to the IRF7455 15A. This device is suitable for applications where the 13A current rating is sufficient. The FDS6670A features lower gate charge (30 nC at 5V) and reduced input capacitance (2220 pF at 15V), which may provide faster switching characteristics in certain circuit topologies. The 8-SOIC package and 30V Vdss rating remain compatible.

Q: Is the FDS8896 a direct equivalent to the IRF7455?

A: The FDS8896 provides the closest electrical match to the IRF7455, with identical 15A continuous drain current and 30V Vdss rating. On-resistance is 6 mOhm at 15A, which is superior to the IRF7455 7.5 mOhm specification. The 8-SOIC package configuration and surface mount type are identical. The FDS8896 is an active product with current manufacturing support, making it suitable for new designs and production continuity.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts listed (DMN3007LSSQ-13, FDS6670A, and FDS8896) are packaged in 8-SOIC with 0.154" (3.90mm) width, maintaining mechanical and footprint compatibility with the IRF7455. Surface mount configuration is identical across all devices.

Q: What compliance certifications apply to the substitute parts?

A: The DMN3007LSSQ-13 and FDS8896 are ROHS3 compliant. All substitute parts are REACH unaffected and carry EAR99 ECCN classification. The FDS6670A compliance status is not specified in the provided data. Verify specific compliance requirements for your application before final component selection.

Q: Can the FDS6670A handle the same current as the IRF7455?

A: No. The FDS6670A is rated for 13A continuous drain current at 25°C, which is 2A below the IRF7455 15A specification. This device is suitable only for applications where the 13A current rating is sufficient. For applications requiring the full 15A capability, use the DMN3007LSSQ-13 or FDS8896.

Q: What is the moisture sensitivity level for all parts?

A: The IRF7455, DMN3007LSSQ-13, and FDS8896 all have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The FDS6670A moisture sensitivity level is not specified in the provided data.
