DMNH4005SCTQ N-Channel 40V 150A MOSFET Equivalent & Substitute Parts

Part Overview

The DMNH4005SCTQ is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 40V drain-to-source voltage with 150A continuous drain current at 25°C. This device is packaged in TO-220-3 through-hole configuration and is designed for high-current switching applications requiring robust thermal performance up to 165W power dissipation. The part maintains Active product status with 805 units currently in stock.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, end-of-life transitions, or when design flexibility permits selection from alternative manufacturers while maintaining electrical and mechanical compatibility within specified parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the DMNH4005SCTQ is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: N-Channel (mandatory match)
• Drain to Source Voltage (Vdss): 40V (exact match required)
• Continuous Drain Current (Id): Minimum 150A at 25°C (equal or greater)
• Rds On (Max): 4 mOhm or lower at specified gate voltage (equal or lower)
• Gate Threshold Voltage (Vgs(th)): 3V or lower at 250µA (equal or lower)
• Power Dissipation: 165W or greater (equal or greater)
• Operating Temperature: -55°C to 175°C (exact match required)
• Mounting Type: Through Hole (mandatory match)
• Package / Case: TO-220-3 (mandatory match)
• Compliance: ROHS3 Compliant, REACH Unaffected (mandatory match)

Substitute Parts Identified:

1. DMNH4005SCT (Diodes Incorporated) — Parametric equivalent with identical electrical specifications and TO-220AB package variant. Product Status: Active. Inventory: 1069 units.

2. IPP80N04S4L04AKSA1 (Infineon Technologies) — Manufacturer-recommended alternative with reduced continuous drain current (80A) and power dissipation (71W). Product Status: Last Time Buy. Inventory: 882 units. This part does not meet the 150A continuous drain current requirement and represents a downgrade in current-handling capability.

Parameter Comparison

Engineering Selection Recommendations

DMNH4005SCT is the primary equivalent substitute for DMNH4005SCTQ. Both parts are manufactured by Diodes Incorporated, maintain Active product status, and satisfy all electrical and mechanical substitution criteria. The DMNH4005SCT features identical continuous drain current (150A), on-resistance (4 mOhm), gate threshold voltage (3V), and power dissipation (165W) specifications. The distinction between DMNH4005SCTQ and DMNH4005SCT lies in the package variant designation (TO-220-3 versus TO-220AB), which represents a minor packaging nomenclature difference without functional impact. Inventory availability for DMNH4005SCT is higher at 1069 units compared to 805 units for the primary part.

IPP80N04S4L04AKSA1 does not qualify as a direct equivalent substitute. Although manufactured by Infineon Technologies and compliant with ROHS3 and REACH requirements, this part fails to meet the continuous drain current specification. The IPP80N04S4L04AKSA1 is rated for 80A continuous drain current, representing a 47% reduction from the required 150A specification. Additionally, power dissipation is limited to 71W compared to the 165W requirement. The Infineon part carries Last Time Buy product status, indicating discontinued manufacturing. Selection of IPP80N04S4L04AKSA1 is appropriate only for applications with reduced current demands below 80A and thermal budgets below 71W.

Frequently Asked Questions (FAQ)

Q: Can DMNH4005SCT be used as a direct replacement for DMNH4005SCTQ?

A: Yes. DMNH4005SCT is a parametric equivalent with identical electrical specifications across all critical parameters: 40V Vdss, 150A continuous drain current, 4 mOhm Rds On, 3V gate threshold voltage, and 165W power dissipation. Both parts are N-Channel MOSFETs in TO-220-3 through-hole packages with identical operating temperature ranges (-55°C to 175°C). The packaging designation difference (TO-220-3 versus TO-220AB) does not affect functional compatibility or pin configuration.

Q: Why is IPP80N04S4L04AKSA1 listed as a manufacturer-recommended substitute if it has lower current rating?

A: IPP80N04S4L04AKSA1 is listed as a manufacturer-recommended alternative in the original part documentation, but it does not meet the electrical requirements of the DMNH4005SCTQ for applications requiring 150A continuous drain current. This part is suitable only for designs with reduced current demands. The Last Time Buy status indicates this Infineon part is being discontinued and should not be selected for new designs requiring long-term availability.

Q: What is the difference between TO-220-3 and TO-220AB package designations?

A: Both designations refer to through-hole TO-220 packages with three leads. The nomenclature difference reflects manufacturer-specific package naming conventions. Mechanically and electrically, both packages are compatible with standard TO-220 footprints and mounting hardware. Pin configuration and thermal performance remain identical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both DMNH4005SCT and IPP80N04S4L04AKSA1 are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the primary DMNH4005SCTQ part. All three parts are suitable for applications requiring environmental compliance with European Union directives.

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

A: All three parts (DMNH4005SCTQ, DMNH4005SCT, and IPP80N04S4L04AKSA1) carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. Standard handling and storage practices are sufficient.

Q: Can these parts be used interchangeably in existing PCB designs?

A: DMNH4005SCTQ and DMNH4005SCT are fully interchangeable in existing designs due to identical pin configuration, package footprint, and electrical specifications. IPP80N04S4L04AKSA1 shares the same TO-220-3 package and pin configuration but must be evaluated for current and power dissipation requirements specific to the application circuit.
