Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPH6R003NL,LQ is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Criteria:

• Drain to Source Voltage (Vdss) must equal or exceed 30V
• Continuous Drain Current (Id) must meet or exceed 38A at 25°C
• On-state resistance (Rds On) must not exceed the specified maximum at rated conditions
• Gate threshold voltage (Vgs(th)) must fall within acceptable operating range
• Gate charge (Qg) and input capacitance (Ciss) must be compatible with drive circuit requirements
• Maximum operating temperature must support 150°C junction temperature operation

Mechanical Compatibility Criteria:

• Surface mount packaging configuration
• 8-pin PowerVDFN package footprint compatibility
• Moisture sensitivity level MSL 1 or equivalent

Compliance Criteria:

• RoHS compliance status (RoHS Compliant or ROHS3 Compliant)
• Active product status for long-term availability

The substitute part DMN3009LFV-7 meets these criteria with enhanced current rating (60A vs. 38A) and improved on-state resistance characteristics, providing superior performance margin within the same voltage class and package family.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TPH6R003NL,LQ): The TPH6R003NL,LQ remains the preferred selection for applications requiring the specified electrical characteristics. This device carries Active product status with RoHS compliance and unlimited moisture sensitivity rating, ensuring long-term availability and environmental regulatory compliance.

Substitute Part Selection (DMN3009LFV-7): The DMN3009LFV-7 from Diodes Incorporated serves as a direct substitute when TPH6R003NL,LQ availability is constrained. This device meets all critical electrical parameters with enhanced current rating (60A vs. 38A) and maintains identical voltage class (30V), package family (8-PowerVDFN), and compliance certifications (ROHS3 Compliant). The substitute provides superior performance margin with lower on-state resistance at higher current levels (5.5mOhm @ 30A vs. 6mOhm @ 19A).

Compatibility Considerations: Both devices operate within the same voltage and current envelope for the specified application class. The substitute part exhibits higher gate charge (42nC vs. 17nC) and input capacitance (2000pF vs. 1400pF), which may require drive circuit evaluation in high-frequency switching applications. Both devices maintain MSL 1 rating and support 150°C junction temperature operation.

Compliance Status: Both parts satisfy RoHS requirements. The TPH6R003NL,LQ carries RoHS Compliant status, while the DMN3009LFV-7 carries ROHS3 Compliant status, both meeting current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can DMN3009LFV-7 be used as a direct replacement for TPH6R003NL,LQ in existing designs?

A: Yes, the DMN3009LFV-7 is electrically and mechanically compatible as a substitute. Both devices share identical 30V voltage rating, 8-PowerVDFN package footprint, and surface mount configuration. The substitute provides higher current capability (60A vs. 38A), making it suitable for applications operating at or below the original part's 38A specification. Drive circuit compatibility should be confirmed due to higher gate charge and input capacitance values.

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

A: The primary differences are: (1) Continuous drain current rating: DMN3009LFV-7 rated at 60A versus TPH6R003NL,LQ at 38A; (2) On-state resistance: DMN3009LFV-7 exhibits 5.5mOhm @ 30A, 10V versus 6mOhm @ 19A, 10V; (3) Gate charge: DMN3009LFV-7 requires 42nC @ 10V versus 17nC @ 10V; (4) Input capacitance: DMN3009LFV-7 has 2000pF @ 15V versus 1400pF @ 15V. Both devices maintain identical 30V Vdss rating and ±20V gate voltage limits.

Q: Are there package compatibility concerns when substituting these parts?

A: Both devices use the 8-PowerVDFN package family with identical footprint dimensions (5x5mm). The TPH6R003NL,LQ is specified as 8-SOP Advance (5x5), while the DMN3009LFV-7 is specified as PowerDI3333-8. These designations refer to the same physical package with compatible PCB land patterns. No layout modifications are required for mechanical substitution.

Q: What is the impact of higher gate charge on circuit performance?

A: The DMN3009LFV-7 requires 42nC of gate charge compared to 17nC for the TPH6R003NL,LQ. This increased gate charge extends the switching time and increases power dissipation in the gate drive circuit. Applications operating at high switching frequencies (above 100kHz) should evaluate whether the existing gate driver can supply the required charge within acceptable time intervals. Low-frequency applications (below 50kHz) typically experience negligible performance impact.

Q: Are both parts RoHS compliant?

A: Yes, both parts meet RoHS requirements. The TPH6R003NL,LQ carries RoHS Compliant certification, while the DMN3009LFV-7 carries ROHS3 Compliant certification. Both certifications satisfy current environmental and regulatory standards for electronic components.

Q: What is the moisture sensitivity rating for these devices?

A: Both the TPH6R003NL,LQ and DMN3009LFV-7 carry MSL 1 (Unlimited) moisture sensitivity level rating. This classification indicates the devices have unlimited shelf life under standard storage conditions and do not require special moisture control measures during handling or storage.

Q: Can the substitute part handle higher power dissipation?

A: The DMN3009LFV-7 is rated for 2W maximum power dissipation at ambient temperature (Ta), compared to 1.6W for the TPH6R003NL,LQ. However, at case temperature (Tc), the TPH6R003NL,LQ is rated for 34W. The substitute part's higher current rating (60A vs. 38A) and lower on-state resistance provide improved thermal performance in high-current applications, though absolute power dissipation ratings should be verified against specific application requirements.

Q: What is the operating temperature range for each device?

A: The TPH6R003NL,LQ operates up to 150°C junction temperature (TJ). The DMN3009LFV-7 operates across a wider range from -55°C to 150°C (TJ). Both devices support the same maximum operating temperature, making them suitable for identical thermal environments. The substitute part provides extended low-temperature operation capability if required by the application.
