• Continuous Drain Current @ 25°C (Ta): 22A
• Continuous Drain Current @ Case Temp (Tc): 100A
• On-State Resistance (Rds On Max): 3.2 mOhm @ 20A, 10V
• Gate Threshold Voltage (Vgs(th) Max): 3V @ 250µA
• Gate Charge (Qg Max): 44 nC @ 10V
• Input Capacitance (Ciss Max): 2370 pF @ 15V
• Power Dissipation: 2.4W (Ta), 62W (Tc)
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Parameters (Must Match):

• Package Type: 8-PowerVDFN (PowerDI3333-8)
• Mounting Type: Surface Mount
• Packaging Format: Tape & Reel (TR)

Compliance & Qualification (Must Match):

• Automotive Grade
• AEC-Q101 Qualification
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The DMT3003LFGQ-13 has two direct parametric equivalents within the DMT3003 base product family that meet all substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DMT3003LFGQ-13, DMT3003LFG-13, and DMT3003LFG-7—are direct parametric equivalents with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Product Status: All three parts are active in production with full AEC-Q101 automotive qualification and ROHS3 compliance, ensuring long-term availability and regulatory acceptance in automotive applications.

Compliance & Certification: Each part carries identical automotive-grade certification and meets all specified compliance requirements (AEC-Q101, ROHS3, REACH Unaffected, MSL 1). No compliance trade-offs exist between the three options.

Inventory Availability: DMT3003LFG-7 has the highest stock level at 13,280 pieces, followed by DMT3003LFG-13 at 10,240 pieces, and DMT3003LFGQ-13 at 10,030 pieces. Inventory levels may influence procurement decisions for high-volume applications.

Functional Interchangeability: The parts are functionally interchangeable in all circuit applications where the DMT3003LFGQ-13 is specified. No circuit redesign, thermal analysis revision, or performance re-qualification is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can DMT3003LFG-13 or DMT3003LFG-7 be used as direct replacements for DMT3003LFGQ-13?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, on-state resistance, gate charge, input capacitance, power dissipation ratings, and operating temperature range. They share the same 8-PowerVDFN package and surface mount configuration. Direct substitution is supported without circuit modification.

Q: Are there any differences in automotive qualification between these parts?

A: No. All three parts carry AEC-Q101 automotive qualification and are classified as automotive-grade components. Regulatory acceptance and long-term availability are equivalent across all three options.

Q: What is the significance of the part number suffix (LFGQ-13 vs. LFG-13 vs. LFG-7)?

A: The suffixes indicate different manufacturing date codes or tape reel configurations within the same base product family (DMT3003). The electrical and mechanical specifications remain identical. The suffix does not affect functional performance or compatibility.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Since all three parts are parametric equivalents with identical specifications, they can be used interchangeably within the same design and assembly process. No separate qualification or testing is required for mixed-part usage.

Q: Are there any thermal or power dissipation differences between these parts?

A: No. All three parts have identical power dissipation ratings of 2.4W at ambient temperature (Ta) and 62W at case temperature (Tc), and share the same operating temperature range of -55°C to 150°C (TJ). Thermal performance is equivalent.

Q: What packaging format is used for all three parts?

A: All three parts are supplied in Tape & Reel (TR) format with 8-PowerVDFN surface mount packages. Reel specifications and tape configurations are identical, enabling seamless integration into automated assembly processes.

Q: Is RoHS compliance the same across all three parts?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. Compliance status and handling requirements are identical.
