DMTH6004LPSQ-13 Equivalent & Substitute Parts

Part Overview

The DMTH6004LPSQ-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 60V drain-to-source voltage with 100A continuous drain current at 25°C (Ta). This device is housed in a PowerDI5060-8 surface mount package and is qualified to AEC-Q101 automotive standards. The part is currently in active production status with 3300 units in stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compliance with automotive and environmental standards. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits alternative packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMTH6004LPSQ-13 is determined by the following critical electrical and mechanical parameters:

Voltage Rating Equivalence: The substitute part must maintain a Vdss rating of 60V or greater to ensure safe operation across all specified application conditions.

Current Handling Capability: The substitute part must support continuous drain current sufficient for the application. The DMTH6004LPSQ-13 specifies 100A at Ta (25°C). Substitute parts with lower Ta ratings but equivalent or higher Tc (case temperature) ratings may be acceptable depending on thermal management design.

On-Resistance Performance: Rds On characteristics must be comparable to ensure similar power dissipation and thermal behavior. The DMTH6004LPSQ-13 specifies 3.1 mOhm maximum at 25A and 10V gate drive.

Gate Drive Compatibility: Gate threshold voltage (Vgs(th)) and maximum gate voltage (Vgs Max) must be compatible with existing driver circuits. Both the main part and substitute must operate within ±20V gate voltage specifications.

Temperature Range: Operating temperature range must support the application environment. The DMTH6004LPSQ-13 operates from -55°C to 175°C (TJ).

Compliance and Qualification: Substitute parts must maintain RoHS3 compliance and automotive-grade qualification status to preserve design certification and regulatory compliance.

Package Compatibility: Physical package dimensions and pin configurations must be compatible with the PCB layout and thermal management design.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The DMTH6004LPSQ-13 remains the preferred choice for applications requiring 100A continuous drain current at 25°C ambient temperature. This part maintains active production status, AEC-Q101 automotive qualification, and ROHS3 compliance. The lower gate charge (47.4 nC) and input capacitance (4515 pF) provide advantages in high-frequency switching applications and reduce driver power requirements.

Substitute Part Consideration: The FDMS86540 from onsemi is electrically compatible for applications where the continuous drain current requirement does not exceed 20A at 25°C ambient or 50A at case temperature. Both parts share identical voltage ratings (60V Vdss), compatible gate drive specifications (±20V maximum), and equivalent on-resistance performance (3.1 mOhm vs. 3.4 mOhm). Both maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Thermal Design Impact: The DMTH6004LPSQ-13 supports higher power dissipation at case temperature (138W vs. 96W), making it suitable for high-current, high-power applications. The FDMS86540 is appropriate for lower-power applications or designs with superior thermal management where case temperature remains controlled.

Temperature Range Consideration: The DMTH6004LPSQ-13 operates to 175°C junction temperature, while the FDMS86540 operates to 150°C. Applications requiring operation above 150°C junction temperature require the primary part.

Gate Drive Compatibility: The FDMS86540 exhibits higher gate threshold voltage (4V vs. 3V) and higher gate charge (90 nC vs. 47.4 nC), requiring verification that existing gate driver circuits can accommodate these parameters without performance degradation.

Packaging and Thermal Management: Both parts use 8-PowerTDFN packages. Physical dimensions and thermal characteristics differ between PowerDI5060-8 and 8-PQFN (5x6) configurations. PCB layout and thermal interface design must be verified for compatibility with the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the FDMS86540 directly replace the DMTH6004LPSQ-13 in all applications?

A: Direct replacement is limited to applications where continuous drain current does not exceed 20A at 25°C ambient temperature. The FDMS86540 supports 50A at case temperature, making it suitable for thermally managed designs. Applications requiring 100A at 25°C ambient require the DMTH6004LPSQ-13.

Q: What are the key electrical differences between these parts?

A: The primary differences are continuous drain current ratings (100A vs. 20A at Ta), gate charge (47.4 nC vs. 90 nC), input capacitance (4515 pF vs. 6435 pF), and maximum junction temperature (175°C vs. 150°C). On-resistance and voltage ratings are equivalent.

Q: Are both parts automotive-qualified?

A: The DMTH6004LPSQ-13 carries AEC-Q101 automotive qualification. The FDMS86540 specification provided does not explicitly state AEC-Q101 qualification. Verification of automotive qualification status is required before substitution in automotive applications.

Q: How do gate drive requirements differ?

A: Both parts accept ±20V maximum gate voltage. The FDMS86540 has higher gate threshold voltage (4V vs. 3V) and higher gate charge (90 nC vs. 47.4 nC). Existing gate driver circuits must be verified to supply sufficient current and voltage to meet the FDMS86540 specifications without performance degradation.

Q: Are the packages physically compatible?

A: Both parts use 8-PowerTDFN package families. However, the DMTH6004LPSQ-13 uses PowerDI5060-8 while the FDMS86540 uses 8-PQFN (5x6). Physical dimensions and pin layouts differ. PCB footprint and thermal interface design must be verified for compatibility.

Q: What is the impact on switching frequency performance?

A: The DMTH6004LPSQ-13 exhibits lower gate charge (47.4 nC) and lower input capacitance (4515 pF), resulting in faster switching transitions and lower driver power dissipation. The FDMS86540 requires higher driver current due to increased gate charge, potentially affecting high-frequency switching performance.

Q: Are both parts RoHS3 compliant?

A: Yes, both the DMTH6004LPSQ-13 and FDMS86540 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What thermal management considerations apply to substitution?

A: The DMTH6004LPSQ-13 supports 138W power dissipation at case temperature versus 96W for the FDMS86540. Applications with high continuous current or limited thermal management must use the DMTH6004LPSQ-13. Thermal interface design, heatsinking, and PCB copper area must be re-evaluated when substituting to the FDMS86540.
