DMNH4005SCT N-Channel 40V 150A MOSFET Equivalent & Substitute Parts

Part Overview

The DMNH4005SCT is an N-Channel metal oxide semiconductor field-effect transistor (MOSFET) manufactured by Diodes Incorporated, rated for 40V drain-to-source voltage and 150A continuous drain current at 25°C. This device is packaged in a TO-220AB through-hole configuration and is designed for high-current switching applications requiring efficient power dissipation up to 165W.

The DMNH4005SCT maintains Active product status and is fully compliant with RoHS3 and REACH regulations. Identifying equivalent and substitute parts is necessary when primary inventory is unavailable, when design requirements demand enhanced performance specifications, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMNH4005SCT is determined by electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 40V
• Continuous Drain Current (Id) must meet or exceed 150A at 25°C
• On-State Resistance (Rds On) must not exceed specified maximum values
• Gate Threshold Voltage (Vgs(th)) must remain within acceptable switching characteristics
• Operating temperature range must encompass -55°C to 175°C

Mechanical Compatibility Criteria:

• Package type must be TO-220AB (through-hole configuration)
• Pin configuration must match TO-220-3 standard
• Mounting type must be through-hole

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required
• Moisture Sensitivity Level (MSL) of 1 (Unlimited) acceptable

The IRF1404PBF qualifies as a substitute part based on these criteria, offering enhanced performance specifications while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

DMNH4005SCT (Primary Selection)

The DMNH4005SCT is the recommended selection for new designs. This device maintains Active product status, ensuring long-term availability and manufacturer support. It meets all RoHS3 and REACH compliance requirements and is suitable for applications requiring 40V, 150A N-Channel MOSFET functionality in TO-220AB packaging.

IRF1404PBF (Substitute Selection)

The IRF1404PBF qualifies as an electrical and mechanical substitute for the DMNH4005SCT. This device provides enhanced performance specifications, including 202A continuous drain current (35% higher than DMNH4005SCT) and 333W power dissipation (2× the DMNH4005SCT rating). Both devices share identical 40V Vdss rating, TO-220AB package configuration, and regulatory compliance status.

The IRF1404PBF carries a "Not For New Designs" product status designation. This classification indicates that Infineon Technologies does not recommend this device for new design implementations. However, the IRF1404PBF remains suitable for replacement, repair, and legacy system applications where the DMNH4005SCT is unavailable.

Selection Criteria:

For new product development, select the DMNH4005SCT. For existing systems requiring component replacement or when DMNH4005SCT inventory is exhausted, the IRF1404PBF provides direct electrical and mechanical compatibility with enhanced performance margins.

Frequently Asked Questions (FAQ)

Q: Can the IRF1404PBF directly replace the DMNH4005SCT in existing circuit designs?

A: Yes. Both devices share identical Drain-to-Source Voltage (40V), TO-220AB package configuration, and through-hole mounting type. The IRF1404PBF provides higher continuous drain current (202A vs. 150A) and greater power dissipation capability (333W vs. 165W), making it electrically and mechanically compatible for direct substitution.

Q: What is the significance of the "Not For New Designs" status on the IRF1404PBF?

A: This designation indicates that Infineon Technologies does not recommend the IRF1404PBF for new product development. However, this status does not affect its suitability for replacement applications, repair operations, or legacy system support where component compatibility is the primary requirement.

Q: Are there differences in gate charge between these devices?

A: Yes. The DMNH4005SCT has a gate charge (Qg) of 48 nC at 10V, while the IRF1404PBF has 196 nC at 10V. Higher gate charge requires longer switching times and increased driver circuit power consumption. Circuit designs must account for this difference in gate drive requirements.

Q: Do both devices require identical thermal management?

A: No. The IRF1404PBF has a maximum power dissipation rating of 333W compared to 165W for the DMNH4005SCT. Applications operating near the DMNH4005SCT's 165W limit may require reduced thermal management requirements when using the IRF1404PBF, due to its higher power handling capability.

Q: Are both devices RoHS3 and REACH compliant?

A: Yes. Both the DMNH4005SCT and IRF1404PBF are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference in input capacitance between these devices?

A: The DMNH4005SCT has an input capacitance (Ciss) of 2846 pF at 20V, while the IRF1404PBF has 5669 pF at 25V. Higher input capacitance increases gate drive circuit complexity and power requirements. Circuit designs must verify gate driver capability when substituting between these devices.

Q: Can the DMNH4005SCT be used as a substitute for the IRF1404PBF?

A: No. The DMNH4005SCT has lower continuous drain current (150A vs. 202A) and lower power dissipation capability (165W vs. 333W). Applications designed for the IRF1404PBF's enhanced specifications may experience performance degradation or thermal stress if the DMNH4005SCT is substituted.
